Families using a freezer bag across meals
A larger plain bag lets you take out the amount needed for fish and chips and keep the rest frozen. Check that the vegetable mix suits the meals you plan to make.
Who is each format for?
Start with the side you want to serve, then consider how you will portion and cook it.
Peas-with-fish diners
If peas are the side you have in mind, a peas-only bag avoids substituting a mix with other vegetables. Follow the directions on the particular pack when cooking from frozen.
Cooks who want separate microwave portions
Steam bags keep portions separate without measuring vegetables from a larger bag. Check the pack’s microwave instructions and which vegetables it contains.
What should you check?
Choose the vegetables you want alongside the meal, then check the pack format and preparation directions.
| Priority | What to check | Your needs |
|---|---|---|
| Vegetable mix | Read the ingredient list: a peas-only bag differs from mixed vegetables, and mixed bags do not all contain the same combination. | For a familiar peas-with-fish side, I would choose plain peas. If I want other vegetables too, I would check the exact mix rather than rely on the pack name. |
| Pack format | Compare pack weights and whether the vegetables come loose in one bag or in separate steam bags. Consider how much you intend to cook at once. | A bag I can portion across several meals suits me; separate bags make more sense when I want a measured microwave side. |
| Cooking method | Check the directions for the exact pack, including the permitted method, microwave wattage and any standing time. Follow warnings about cooking from frozen. | If I am using the microwave while preparing fish and chips, I need a pack with directions for my appliance. Otherwise, I can choose a format with a suitable hob method. |
| Portions and labels | Check the serving amount, ingredients and nutrition panel, particularly on seasoned mixes. The NHS says 80g of frozen vegetables counts as one 5 A Day portion. | I want to serve an amount that fits the meal and know whether the bag contains only vegetables or added ingredients such as butter or seasoning. |
Common buying mistakes
-
Assuming every mixed bag contains the same vegetables
A mixed bag may not give you the peas-led side you expected. Sainsbury’s Stamford Street mix lists carrots, cauliflower, peas and green beans, while Waitrose Essential Mixed Vegetables lists carrots, peas, green beans and sweetcorn.
Read the ingredients on the pack and choose the combination you want with fish and chips.
-
Treating frozen vegetables as ready to eat
Cooking instructions vary by product. Birds Eye says its garden peas must be cooked straight from frozen and must not be eaten raw or defrosted; M&S describes its organic mixed vegetables as a raw product that must be cooked.
Follow the exact pack’s cooking, storage and refreezing instructions, and check that the vegetables are piping hot before serving.
-
Assuming a vegetable mix contains only vegetables
Some prepared mixes include added ingredients. ASDA’s listing for Aunt Bessie’s Green Vegetable Mix includes butter, stock and oil, while Sainsbury’s describes a garlic-and-herb butter in its listing.
Check the current pack’s ingredients and allergen information if you want a plain side or need to avoid a particular ingredient.
Brand and retailer ranges
These ranges illustrate different vegetable mixes and pack formats; check the individual product rather than assuming every item in a range is prepared alike.
Birds Eye
Birds Eye offers garden peas as well as mixed-vegetable formats for shoppers considering a peas-only or portioned side.
- Its garden-pea instructions say to cook straight from frozen.
- Those pea instructions should not be assumed to apply to every Birds Eye vegetable mix; check the chosen pack.
Tesco
Tesco lists a 1kg own-label mixed-vegetable bag alongside other frozen-vegetable formats.
- The 1kg bag provides a loose-bag option to compare with portioned formats.
- Check each product’s ingredients and directions rather than treating the range as one interchangeable mix.
Sainsbury’s
Sainsbury’s lists distinct 1kg vegetable mixes, including Stamford Street Mixed Vegetables and Classic Vegetable Mix.
- Stamford Street lists carrots, cauliflower, peas and green beans.
- The Classic mix lists carrot, broccoli and cauliflower, so it is not a substitute for a peas-containing mix if peas are what you want.
Asda
Asda lists a 1kg mixed-vegetable bag and a separate cauliflower, broccoli and carrot mix.
- The cauliflower, broccoli and carrot product states the proportions of its three vegetables.
- Check the ingredients of the specific bag before choosing it as a peas-with-fish side.
Waitrose
Waitrose lists Essential Mixed Vegetables and a separate chunky cauliflower, broccoli and carrot mix.
- Essential Mixed Vegetables lists carrots, peas, green beans and sweetcorn.
- The chunky mix has a different composition; use the packet label for the current ingredients.
M&S
M&S lists a frozen-vegetable range that includes organic mixed vegetables.
- Its organic mixed-vegetable page gives cooking and frozen-storage information.
- M&S states that this product is raw and must be cooked; follow its pack directions before serving.

Questions about frozen vegetables
Should I choose peas or mixed vegetables with fish and chips?
Choose plain peas if you want a peas-only side. Choose a mixed bag if you want other vegetables alongside them, but read its ingredients: some mixes contain peas and others do not.
Do frozen vegetables count towards 5 A Day?
Yes. The NHS says 80g of frozen vegetables counts as one 5 A Day portion. Check the serving amount you put on the plate rather than assuming a whole bag or steam pouch is one portion.
Can I cook frozen peas or mixed vegetables in the microwave?
Use the microwave only when the exact pack gives directions for it, and follow its wattage and timing guidance. Birds Eye Garden Peas 800g list a microwave method; other packs may have different instructions.
Can frozen vegetables be eaten without cooking?
Do not assume they are ready to eat. Birds Eye instructs shoppers to cook its garden peas straight from frozen, not eat them raw or defrosted; M&S says its organic mixed vegetables are raw and must be cooked. Follow the instructions for your particular pack.
What should I check on a seasoned vegetable mix?
Read the current pack’s ingredients and allergen information as well as its cooking directions. Some prepared mixes contain butter, stock or seasoning, so a vegetable mix is not necessarily vegetables alone.
