Lunch planners who want one complete meal
A single-serving frozen ready meal keeps assembly to a minimum. Check its nutrition for the serving you will eat, as well as whether its cooking method fits your lunch break.
Who are these options for?
Plant-based meal-preppers
A frozen ingredient such as Linda McCartney’s Vegan Vegemince can form part of a lunch you assemble yourself. The Waitrose & Partners listing gives nutrition after frying per 100g; it does not describe the product as a complete prepared meal.
Shoppers stocking several freezer lunches
When buying multiples, compare nutrition on the same portion basis and check each pack’s storage and cooking directions. A meal that needs an oven may not work where only a microwave is available.
What should you check before stocking up?
Start with whether you need a complete lunch or ingredients to assemble one, then compare portions, preparation and storage instructions.
| Priority | What to check | Your needs |
|---|---|---|
| Nutrition per portion | Compare the amount you would eat, not just figures per 100g. The Food Standards Agency explains that traffic-light labels show whether fat, saturated fat, sugars and salt are high, medium or low. | I want to compare lunches on a like-for-like serving basis, rather than rely on a calorie or protein claim alone. |
| Meal or ingredient | Check whether the pack is a prepared meal or one component. For an assembled lunch, consider what vegetables and other foods you will add. | If I choose a frozen protein or vegetable mix, I need a plan for the rest of lunch. |
| Cooking method | Check the required appliance, cooking time and any defrosting or standing instructions on the exact pack. | At work I may have only a microwave, or too little time for an oven-cooked meal. |
| Freezer storage | Confirm that the exact product is suitable for freezing and follow its storage and refreezing directions. | Before buying several lunches, I want to know that each one can stay in my freezer until I intend to use it. |
What can go wrong when choosing freezer lunches?
-
Treating one label claim as the whole nutrition picture
Terms such as “under 500 calories”, “calorie controlled”, vegan or high protein do not tell you everything about a serving’s salt, saturated fat or place in a complete lunch.
Compare the full nutrition information on the same portion basis, then check whether the product is a meal or needs accompaniments.
-
Assuming a chilled ready meal can be frozen
M&S states that its Count On Us Cod Fillets with Potato and Pea Crush is not suitable for freezing. A range name does not establish the storage instructions for every product in it.
Read the directions for the exact pack before buying multiples for the freezer.
-
Overlooking the equipment needed at lunchtime
Waitrose & Partners’ instructions for Kirsty’s Frozen Vegetable Lasagne require 45 minutes in an oven, which does not fit a microwave-only lunch break.
Check the appliance and full cooking directions before choosing a meal for a particular location.
-
Checking calories but overlooking salt
Waitrose & Partners lists Kirsty’s lasagne at 230 kcal and 1.22g salt per 283g oven-baked serving; its salt traffic light is medium.
Read the salt value alongside calories and the other nutrition information for the portion you plan to eat.
Which retailers offer useful starting points?
Retailer categories can help narrow a search, but the exact product label determines its nutrition, cooking method and freezer suitability.
Waitrose
Waitrose & Partners lists both complete frozen meals and frozen ingredients, including Kirsty’s lasagne and Linda McCartney’s Vegan Vegemince.
- Their product listings give nutrition on stated serving or preparation bases, alongside storage and cooking information.
- Check the pack when you buy: Waitrose & Partners advises that product information can change.
Tesco
Tesco Groceries includes an “Under 500cal Meals” filter in its frozen ready-meal category.
- The filter offers a starting point for narrowing the ready-meal range.
- Check each shortlisted meal’s full nutrition panel and serving size; the filter alone does not assess the whole lunch.
ASDA
ASDA Groceries has frozen ready-meal categories, including a “Better For You Frozen Ready Meals” route.
- The category provides a way to browse frozen meals separately from other freezer foods.
- A category description does not replace checking nutrition and cooking instructions for the chosen product.
M&S
M&S lists vegetarian and vegan choices in its frozen ready-meal range and describes its Count On Us range as calorie controlled.
- The frozen range offers dietary filters that can help narrow choices.
- Do not assume a Count On Us meal belongs in the freezer: M&S states that its Cod Fillets with Potato and Pea Crush is not suitable for freezing.
Iceland
Iceland Foods lists frozen ready meals and says its MyProtein ready-meal range can be cooked from frozen.
- The frozen-ready-meal category gives shoppers a direct route to meals intended for freezer storage.
- Check the individual product’s serving size, nutrition and cooking directions before comparing it with another lunch.
Sainsbury’s
Sainsbury’s lists calorie-counted vegetarian ready meals, including Mediterranean Vegetable Style Pasta and Spinach & Ricotta Cannelloni, in its chilled listings.
- The listings identify named vegetarian meals for shoppers comparing ready-meal options.
- Their appearance in a chilled category does not establish that those exact meals can be frozen at home; check each pack.

Freezer lunch questions
What should I compare on frozen lunch labels?
Compare nutrition for the serving you intend to eat, including calories, fat, saturated fat, sugars and salt, then consider what else makes up the lunch. The Food Standards Agency explains that traffic-light labels show whether fat, saturated fat, sugars and salt are high, medium or low; a single calorie claim does not describe the whole meal.
Can Kirsty’s Frozen Vegetable Lasagne be prepared in a microwave?
No. The Waitrose & Partners instructions specify oven cooking from frozen for 45 minutes at 200°C, or 180°C in a fan oven, followed by a one-minute stand. Check the pack instructions before cooking and make sure the meal is piping hot throughout.
Is Linda McCartney’s Vegan Vegemince a complete lunch?
No; it is a frozen ingredient for a lunch you assemble. Add other foods, such as vegetables and a starchy accompaniment, and compare the nutrition for the amount you prepare. Waitrose & Partners reports its protein and salt values per 100g after frying, not for a complete lunch.
Can I freeze any chilled calorie-controlled ready meal?
No. Check the exact pack before putting a chilled meal in the freezer: M&S states that its Count On Us Cod Fillets with Potato and Pea Crush is not suitable for freezing. Follow the product’s stated storage and use-by directions.
What storage instructions matter when buying several frozen lunches?
Follow each product’s stated storage, defrosting and cooking directions rather than applying one meal’s instructions to another. Waitrose & Partners specifies storage at −18°C for Kirsty’s Frozen Vegetable Lasagne and says not to refreeze it after defrosting.
