Canteen managers planning portions
Set a repeatable serving size, then compare the calories, salt and saturated fat in that serving. Keep the current product information available for menu planning and allergen communication.
Who is this for?
Workers choosing a pizza lunch
A labelled half-pizza portion offers a clearer basis for comparing lunches than treating a pizza labelled as two servings as one meal. The rest of the plate matters too, so consider any side alongside the pizza portion.
Canteen customers with dietary requirements
Vegetarian, vegan and gluten-free variants serve different requirements; the style of pizza alone cannot establish suitability. Check the exact product and ask the canteen for its current allergen information.
What should you check first?
Start with the portion the canteen intends to plate. Then assess its nutrition, dietary suitability and fit with the kitchen’s service process.
| Priority | What to check | Your needs |
|---|---|---|
| Served portion | Check servings per pizza and kcal for the portion plated. Use per-100g figures as a separate comparison, not as the calorie count for lunch. | I want to know what a half pizza or slice contributes to my lunch, rather than compare packs that may be served in different amounts. Sainsbury’s labels identify two servings in each of the three half-pizza examples discussed here. |
| Salt and saturates | Compare both values for the same served portion as the calorie figure. Sainsbury’s labels for the three examples show 1.58–1.8 g salt and 5–6.9 g saturates per half pizza. | A lower kcal figure alone is not enough for my choice: I also want to compare the salt and saturated fat on the plate. |
| Dietary suitability | Check the exact variant’s ingredients, dietary description and current allergen information. Account for the canteen’s handling and service process. | If I need a vegetarian, vegan or gluten-free option, I need information about the pizza actually served, not an assumption based on its name or crust. |
| Kitchen process | Read the pack’s cooking method and instructions. Under GOV.UK guidance, food must be fully defrosted before cooking unless the manufacturer says to cook it from frozen; check equipment and service capacity too. | I need a lunch the canteen can prepare according to its instructions and serve through its usual food-safety process. |
What can go wrong when choosing?
-
Comparing per 100g, then serving the whole pizza
A per-100g figure does not describe a larger plated portion. The three pizzas with half-pizza figures cited here are each labelled as two servings, so serving the whole pizza changes the calorie comparison.
Decide the serving size first and compare kcal, salt and saturates for that amount. Use the same portion standard when planning the menu.
-
Assuming thin, vegetarian or wood-fired means fewer calories
These descriptions identify a style or dietary option, not a calorie value. Sainsbury’s labels give 423 kcal and 432 kcal per half pizza for the two mozzarella examples discussed here.
Shortlist by the style customers need, then compare the current nutrition panel for each exact product and intended serving.
-
Relying on the menu name for allergen information
Recipes and suppliers can change. The Food Standards Agency says retail and catering food businesses must provide allergen information and follow applicable labelling rules.
Keep allergen information tied to the product being served, and make sure service staff can access it when customers ask.
-
Ordering before checking cooking instructions
A frozen pizza may not fit the canteen’s equipment or the time available at lunch service. Its cooking instructions also determine whether it should be defrosted first.
Check the current pack, available equipment and expected throughput before putting the pizza into the canteen’s food-safety and service plan.
Which brands offer relevant options?
These brand and retailer examples show different pizza formats and dietary variants; the nutrition decision still belongs to the exact product and serving size.
Dr. Oetker Ristorante
Its listed range includes thin-and-crispy pizzas alongside separately identified vegan and gluten-free variants.
- Sainsbury’s lists the Hawaii pizza at 387 kcal and the Mozzarella pizza at 432 kcal per labelled half pizza.
- Those figures do not describe every flavour. Check salt, saturates, allergens and the current label for the variant being served.
Sainsbury’s
Its Taste the Difference Mozzarella & Marinated Cherry Tomato Wood Fired Pizza is a vegetarian tomato-and-mozzarella example.
- Sainsbury’s labels a half pizza as 423 kcal, 1.58 g salt and 6.9 g saturates.
- Wood-fired styling does not determine calorie content; compare the portion and current nutrition label.
Goodfella’s
Retailer listings identify stonebaked thin, deep-pan and gluten-free pizzas in the range.
- The different formats allow a canteen to consider portion plans and dietary variants separately.
- A thin base or a gluten-free description does not establish the calories, salt or saturates in a serving.
Chicago Town
Listings include large takeaway-style pizzas with stuffed crusts and pepperoni toppings.
- A large-format pizza can be considered where the canteen plans a shareable serving.
- Assess the exact product’s nutrition for the portion served rather than treating its format as a lower-calorie option.
Tesco
Tesco’s free-from pizza listings include named Goodfella’s and Dr. Oetker gluten-free variants.
- The listings provide specific variants to check when a gluten-free product is required.
- Check the precise product’s current ingredients, allergens and nutrition before using it in a canteen menu.
Frozen pizza options on Joybuy
These options include two thin-base pizzas and a stuffed-crust pizza. Compare the portion you intend to serve; the product styles alone do not settle which lunch meets a canteen’s calorie criteria.

Dr. Oetker Ristorante Hawaii Pizza 355g
For a half-pizza canteen serving, Sainsbury’s label lists 387 kcal, 5 g saturates and 1.8 g salt. This is a thin-and-crispy pizza; check the current pack’s allergens and cooking instructions before service.
No image available
Chicago Town Takeaway Stuffed Crust BBQ Chicken 668g
The BBQ sauce-filled stuffed crust makes portion size particularly important for this canteen choice. Compare the current pack’s kcal, salt and saturates for the amount you intend to serve, and follow its cooking and allergen information.
No image available
Goodfella’s Pepperoni Stonebaked Thin 332g
This pepperoni pizza has a stonebaked thin base. If the canteen plans to serve half a pizza, compare the current pack’s nutrition for that portion, including salt and saturates, rather than assuming the thin base determines its calorie content.
Common questions
How should a canteen compare frozen pizzas for a lower-calorie lunch?
Compare kcal for the portion the canteen will serve, then check salt and saturates for that same amount. A per-100g figure is useful for comparing energy density but does not tell you the calories in a plated lunch; the three Sainsbury’s-labelled examples discussed here each declare two servings per pizza.
Does a thin crust mean a pizza is lower calorie?
No: crust style alone cannot establish the calories in a serving. Check the exact pizza’s current nutrition panel and planned portion, including its toppings, salt and saturated fat.
Can a workplace canteen cook pizza straight from frozen?
Only when the manufacturer’s instructions permit cooking that product from frozen. GOV.UK guidance says food must otherwise be fully defrosted before cooking; follow the pack instructions and the canteen’s food-safety procedures.
What allergen information does a canteen need for pizza?
The Food Standards Agency says retail and catering food businesses must provide allergen information and follow applicable labelling rules. Keep information for the exact pizza being served accessible to staff and customers, including when products or suppliers change.
Does vegetarian, vegan or gluten-free mean lower calorie?
No. Those descriptions address different dietary requirements, not the calories in a serving. Check the exact product’s current nutrition, ingredients and allergen information, together with how the canteen will handle and serve it.
