Lunch shoppers using a calorie allowance
If one pack will be your lunch, the calories for the amount you eat matter more than a per-100g figure alone.
Who is this lunch choice for?
Shoppers with a short lunch break
A frozen meal needs to suit your available microwave or oven and the time you have. Salt, saturated fat and serving size still deserve a look alongside the cooking directions.
Shoppers with protein or dietary requirements
If protein content, ingredients or allergens affect your choice, check them on the particular meal. A range described as high protein does not establish its calories or allergen suitability.
What matters on the pack?
Start with the portion you expect to eat, then compare nutrition and preparation details between meals that could work for your lunch.
| Priority | What to check | Your needs |
|---|---|---|
| Calories and portion | Read kcal per portion and the number of portions in the pack. Use per-100g figures to compare meals of different sizes. Tesco Groceries’ frozen “Under 500cal Meals” category is a starting filter, not a substitute for the individual label. | I want to know the calories in the amount I will actually eat, especially if the pack contains more than one portion. |
| Salt and saturates | Compare salt and saturated fat on the same basis, including per portion where shown. NHS food-label guidance identifies both among the nutrients shown on nutrition labels. | A lower calorie count alone will not answer my questions about the rest of the meal’s nutrition. |
| Ingredients and allergens | Read the current pack’s ingredients and emphasised allergens. Check the individual product rather than relying on a vegan, calorie-controlled or high-protein range name. | If an ingredient or allergen matters to me, I need the details for this meal, not an assumption based on its range. |
| Cooking and storage | Confirm frozen storage, the available cooking method and the pack’s time, settings and standing instructions. Iceland Foods lists different microwave and oven times for its Slimming World Chicken Tikka Masala. | Will I have the right appliance and enough time to prepare this lunch according to its instructions? |
Common buying mistakes
-
Assuming a calorie category answers every nutrition question
A meal’s calories do not tell you its salt or saturated-fat content.
Use a category such as Tesco Groceries’ frozen “Under 500cal Meals” to make a shortlist, then compare the chosen packs’ nutrition labels.
-
Comparing only calories per 100g
Per-100g values make products easier to compare, but the amount you eat may be larger or smaller than 100g or the stated portion.
Check how many portions the pack contains and calculate your lunch choice from the portion you intend to eat.
-
Relying on a range name for allergen suitability
A dietary or calorie-focused description does not replace the ingredients and allergen information for the particular product. Iceland Foods cautions that its online product information can change.
Check the current physical pack’s ingredients and emphasised allergens before preparing or eating the meal.
-
Assuming every frozen meal fits the lunch break
Microwave and oven methods can take different amounts of time; Iceland Foods lists both for its Slimming World Chicken Tikka Masala.
Check the meal’s appliance settings, cooking time, standing instructions and storage directions before choosing it.
Retailer ranges worth checking
These retailer ranges offer different ways to narrow a lunch search; check the storage format and nutrition of the specific meal you choose.
Tesco
Tesco Groceries lists an “Under 500cal Meals” category within frozen ready meals, including Tesco Calorie Controlled dishes.
- An explicit frozen-meal calorie category can help narrow the options.
- The category name does not establish a meal’s salt, saturated fat, ingredients or allergen suitability.
Iceland
Iceland Foods offers frozen Slimming World meals and describes its MyProtein ready meals as cook-from-frozen options.
- The ranges include ready-meal and lunch-bowl formats.
- Check each pack’s calories and other nutrition values; Iceland Foods says online ingredients, nutrition and allergy details may change.
M&S
Marks & Spencer describes its Count On Us dishes as calorie controlled and lists other health-positioned ready-meal ranges.
- The ready-meal ranges provide a starting point for comparing labelled portions.
- If frozen storage is essential, confirm that the particular meal is sold frozen and check its nutrition label.
Waitrose
Waitrose & Partners lists frozen ready meals and separately uses a Good Health label on selected products.
- Its frozen range includes dishes such as lasagne, cottage pie and chicken tikka masala.
- Do not assume a frozen meal carries the Good Health label or fits a calorie allowance; inspect the individual product.

Frozen meal questions
Does “under 500 calories” tell me everything I need to know about a frozen lunch?
No. Tesco Groceries’ frozen “Under 500cal Meals” category is a useful starting filter, but check the calories for the amount you will eat and compare salt and saturated fat on the individual pack.
Should I compare figures per 100g or per meal?
Use per-100g figures to compare products on the same basis, then use the per-portion or whole-pack figures to assess the lunch you intend to eat. Check whether the stated portion matches your serving.
Do I need to check allergens on a vegan or calorie-controlled meal?
Yes. Read the particular pack’s ingredients and emphasised allergens rather than treating a dietary range name as an allergen guarantee. Iceland Foods also cautions that online ingredients and allergy information can change.
Can I microwave any frozen ready meal for lunch?
Do not assume so. Check the specific pack for its permitted cooking methods, settings, time and standing instructions; microwave and oven directions can differ substantially.
What should I recheck when an online order arrives?
Read the physical pack’s portion nutrition, ingredients, allergens, storage directions and cooking instructions. Iceland Foods warns that online product information, including nutrition and allergy details, can change.
