People cooking for one
A single pack with a stated prepared-pack calorie total is easier to compare with other meals for one than a figure given only per 100 g. Tesco Groceries lists 293 kcal per prepared pack for its Health Chicken Curry and Rice.
Who this choice matters to
The right pack depends on whether your main concern is a known dinner-sized portion, its wider nutrition details or its ingredients.
Shoppers comparing protein as well as calories
If a meal closer to 370 kcal fits what you are looking for, the two Birds Eye Get Real Protein bowls listed by Waitrose & Partners each state 35 g protein and two portions of fruit and vegetables per bowl. Compare their full-bowl figures, not just the protein on the front of the pack.
People checking ingredients or allergens
Inspect the current pack for the exact meal before buying and eating it. A familiar product name or an earlier online listing is no substitute for its ingredient and allergen declaration.
What to check before buying
Start with the amount you will eat, then compare meals on the same prepared-portion basis before checking nutrition and cooking practicality.
| Priority | What to check | Your needs |
|---|---|---|
| Calories and portion | Check the calories per prepared pack or serving, how many servings the pack contains, and whether the figure is for the cooked meal. | I am eating the whole tray, so I need its full-meal calorie figure rather than relying on the per-100 g number. |
| Nutrition beyond calories | Compare protein, vegetables, salt, saturated fat and fibre using the stated serving and nutrition table. Read traffic-light colours alongside the figures they describe. | A lower calorie total is one consideration; I also want to see what else the meal contains. Waitrose & Partners lists 35 g protein per bowl for each of the two Birds Eye examples, alongside medium salt ratings. |
| Cooking method | Check the required microwave wattage or oven method, total cooking time, and any stirring or standing steps. | I need a dinner I can prepare with the appliance available tonight, including the full time stated on the pack. |
| Ingredients and allergens | Read the current pack’s ingredients, emphasised allergens and any relevant precautionary statements for the exact meal. | If I avoid an ingredient, I need to check this pack rather than assume that another meal in the range has the same recipe. |
Common buying mistakes
-
Comparing per 100 g, then eating the whole tray
A per-100 g figure does not tell you the calories in the portion you will eat. Tesco Groceries states 293 kcal per prepared pack for its chicken curry, while Waitrose & Partners states 368 kcal and 373 kcal per microwaved bowl for the two Birds Eye meals.
Compare the calorie total for the intended portion and check the serving count and preparation basis.
-
Assuming fewer calories means less salt
In its May 2025 review of 1,511 chilled and frozen ready meals from 11 major retailers, Action on Salt & Sugar reported that 56% were high in salt, 42% high in saturated fat and 71% low in fibre. Those are findings about products assessed, not about every frozen meal.
When comparing meals with similar calorie totals, read their salt, saturated fat and fibre figures as well as any traffic-light labels.
-
Counting only the microwave heating time
Instructions can also require stirring and standing. GOV.UK advises following packet instructions and making sure food is steaming hot throughout.
Check the instructions against your microwave’s wattage before buying, then follow every heating and standing step on the pack.
-
Taking a range name as a guarantee about the meal
M&S describes Count On Us dishes as calorie controlled, but its separate frozen ready-meal range does not establish that every Count On Us dish is frozen. A range name also cannot tell you the ingredients in the particular pack you pick up.
Confirm that the exact product is frozen, then read its portion, nutrition, ingredient and storage information.
Brand ranges and meal examples
These examples illustrate different starting points for checking individual frozen meals; a range description does not establish the details of every product in it.
Tesco
Tesco Groceries lists Health Chicken Curry and Rice as a frozen meal for one in its Under 500cal Meals category.
- The listing states 293 kcal, 17 g protein and 1.07 g salt per prepared pack, with the salt rated medium.
- Those figures describe this chicken curry, not Tesco’s wider frozen range. Check the current listing if you want this particular meal.
Birds Eye
Waitrose & Partners lists two Birds Eye Get Real Protein frozen bowls with stated whole-bowl nutrition figures.
- The Thai Red Chicken Curry states 368 kcal per bowl and the Mexican Style Chicken Burrito Bowl 373 kcal; each states 35 g protein and two portions of fruit and vegetables.
- Their listed salt figures are 1.80 g and 1.60 g per serving respectively, both rated medium. Check current availability before planning dinner around either bowl.
M&S
M&S describes Count On Us as a calorie-controlled range and also has a separate frozen ready-meal range.
- Count On Us offers a starting point when looking for meals with stated portion information.
- The frozen range page does not establish that Count On Us dishes are frozen. Check the format and nutrition of the exact product.
Iceland
Iceland lists Myprotein Salt & Pepper Chicken with Rice as a frozen microwave meal.
- The product listing gives an eight-minute microwave method for the 350 g meal.
- Its ingredient information identifies egg, soya, wheat, barley and sesame, and the listing says it is not suitable for a low-potassium diet. Read the current pack and its calorie figure before deciding whether it meets your requirements.

Questions about frozen ready meals
How do I judge whether a frozen meal is lower calorie for dinner?
Compare the calories in the prepared portion you will actually eat, rather than using a per-100 g figure alone. For context, Tesco Groceries lists 293 kcal per prepared pack for its Health Chicken Curry and Rice, while Waitrose & Partners lists 368 kcal and 373 kcal per bowl for two Birds Eye Get Real Protein meals. Check serving size and the other nutrition figures before choosing.
Does more protein mean a frozen meal has fewer calories?
No. The two Birds Eye bowls listed by Waitrose & Partners each state 35 g protein, alongside whole-bowl totals of 368 kcal and 373 kcal. Compare both figures, plus the serving size and salt information, against what matters to you.
What should I check before microwaving a frozen ready meal?
Follow the exact pack instructions for your microwave wattage, including any stirring and standing steps. GOV.UK advises following packet instructions and checking that food is steaming hot throughout, rather than judging it by hot edges alone.
Where should I check allergens in a prepacked frozen meal?
Read the ingredients and emphasised allergens on the current pack. GOV.UK guidance for prepacked food in England, Northern Ireland and Wales requires allergen information; an older online listing should not replace a check of the product you have.
Can I rely on the nutrition details from a previous order?
Check the current pack before cooking and eating. Product information can change, so an earlier order or online description may not reflect the ingredients and nutrition of the meal in front of you.
