Choose a frozen ready meal for a festival only if the amount you will eat is under 500 kcal and you can follow its storage and cooking instructions throughout the trip. Without dependable cold storage and suitable heating equipment, choose food that does not require freezing instead: the Food Standards Agency warns that a cool box is unlikely to keep food chilled for an extended period.
A frozen meal is an option if you can meet its labelled storage conditions during travel and at the festival, then cook it using the required equipment. Check the kcal for the whole pack or the portion you intend to eat.
If your limit is under 500 kcal, match the nutrition figure to the amount you will eat. The NHS notes that labels may show kcal per 100 g or per portion, and the manufacturer’s portion may differ from yours.
Plan around food that does not need extended chilled or frozen storage. The Food Standards Agency suggests predominantly dry foods when food cannot be stored sufficiently during a camping trip; check the calories of any alternative separately.
Decide how the food will be stored and prepared before shortlisting meals by their calorie labels.
Consider it: When your travel and festival arrangements can meet the pack’s frozen-storage and cooking instructions.
Trade-off: The meal depends on suitable storage and heating equipment throughout the trip.
Consider it: When you will eat before leaving, or have accommodation that meets the meal’s refrigeration and heating requirements.
Trade-off: Chilled and frozen meals are not interchangeable. M&S labels its Count On Us Piri Piri Chicken for refrigeration at 0°C to +5°C and says it is not suitable for freezing.
Consider it: When you cannot keep a ready meal at its required temperature for the trip.
Trade-off: Check portions and kcal afresh rather than assuming an alternative meets the same under-500-kcal target.
| Priority | What to check | Your needs |
|---|---|---|
| Portion calories | Read kcal per pack or per portion and the number of portions. If only kcal per 100 g is shown, use it with the weight you will eat. | I want the amount I actually eat to be under 500 kcal, not just a labelled portion that is smaller than my meal. |
| Cold storage | Read the pack’s storage temperature and check whether you can maintain it during transport and the stay. The Food Standards Agency warns that a cool box is unlikely to keep food chilled for an extended period. | A frozen meal only works for my trip if I have dependable storage for the entire time it needs to remain frozen. |
| Cooking access | Check the appliance, cooking time and preparation instructions on the pack against the facilities you can use. | Before packing a ready meal, I need to know I can prepare it as directed where I plan to eat. |
| Ingredients and allergens | Read the current pack’s ingredient and allergen statements, as well as its nutrition and storage instructions. | If I need to avoid an ingredient, the label on the particular meal I buy matters more than a range name or category filter. |
A pack heavier than 100 g contains more than one 100 g measure, so that figure alone cannot establish whether the amount you eat is under 500 kcal.
Use the full-pack figure if you will eat the whole pack. Otherwise, calculate kcal from the per-100-g figure and the weight of your portion; the NHS cautions that a manufacturer’s portion may not match yours.

Take a frozen or chilled meal only if you can meet its labelled storage conditions throughout the trip. Otherwise, choose food that does not depend on that storage.
A category such as Tesco’s “Under 500cal Meals” can help narrow a search, but the category name does not tell you whether the amount you plan to eat is under 500 kcal.
Check the particular pack’s kcal, number of servings, ingredients, allergens and preparation instructions.
A ready meal is not a practical festival choice if you cannot use the appliance required by its instructions.
Confirm the available cooking equipment, then compare it with the pack’s method and timing before buying.
These ranges offer different starting points; check each meal’s label before treating it as a frozen, under-500-kcal option.
Tesco Groceries lists an “Under 500cal Meals” subcategory within frozen ready meals.
M&S describes its Count On Us range as calorie controlled, but the range name does not establish that a particular meal is frozen.
Waitrose & Partners lists frozen ready meals including 400 g beef lasagne, cottage pie and vegetable lasagne.
Sainsbury’s groups frozen ready meals into categories including traditional, Indian, Italian, fish and free-from options.
Iceland Foods has a frozen ready-meal range and an Iceland-exclusive Slimming World range.
This frozen ready meal is relevant if your festival arrangements can meet the storage and cooking directions on its pack. Check its current portion calories before choosing it for an under-500-kcal meal.

For a festival trip, choose this 350g meal only if you can follow its frozen-storage and cooking directions. Check the current pack for kcal for the amount you will eat, allergens and the required heating method.
No: compare 500 kcal with the amount you will actually eat. The NHS notes that labels may show kcal per 100 g or per portion, while the manufacturer’s portion may differ from yours; use the pack weight and per-100-g figure if you need to calculate your portion.
Do not assume it can. The Food Standards Agency warns that a cool box is unlikely to keep food chilled for an extended period, so take a frozen meal only if your arrangements can meet its labelled storage conditions throughout the trip.
Check the pack’s required appliance, cooking method and timing against the facilities you will have. Check its storage instructions too: access to heating equipment does not solve a cold-storage problem during travel or the stay.
Only if that individual meal’s instructions permit it. For example, M&S labels its Count On Us Piri Piri Chicken for refrigeration at 0°C to +5°C and states that it is not suitable for freezing.
Use it to shortlist meals, then check the individual pack. The kcal figure needs to match the portion you will eat, and the storage, cooking, ingredient and allergen information needs to suit your trip and requirements.
