Who is each approach for?

Households stocking up for several meals

If pie night is one of several meals you are planning, loose bags let you take out different amounts each time. Make room for both packs and keep opened bags securely closed in the freezer.

Microwave-first cooks

Steam bags offer portioned preparation without measuring vegetables into a pan. Check the pack’s microwave method and take care when opening a hot bag.

Shoppers choosing a particular vegetable mix

Peas or peas and sweetcorn give the meal a familiar side. If you want a different combination, read the ingredients: standard mixes and broccoli-and-cauliflower medleys contain different vegetables.

What should you check before buying two packs?

Choose the vegetables you want with pie and mash, then check whether their pack formats suit the space and cooking routine you have.

PriorityWhat to checkYour needs
Freezer space Check the combined pack sizes and the space available to store them. The checked product instructions specify frozen storage at −18°C or cooler. Two large bags would be useful for later meals, but I need room to store both and manage them after opening.
Pack format Compare loose bags, which allow variable portions, with individually portioned microwave steam bags. Check how many bags are inside a multipack. I may want different amounts for different meals, or ready-portioned bags for a microwave-led evening.
Vegetable mix Read the ingredients rather than relying on the pack picture. Waitrose Essential Mixed Vegetables lists carrots, peas, green beans and sweetcorn; the M&S British Vegetable Medley lists broccoli, cauliflower, peas and Chantenay carrots. For this pie and mash, I might choose peas as a familiar side; for later meals, I might prefer a broader mix.
Cooking method Check whether the exact pack has hob, microwave or steam-bag instructions. Birds Eye instructs cooks not to pierce its Steamfresh Super Sunshine bag before microwaving. If I am using only the microwave, both packs need preparation instructions that work with it.
Meal portions Consider how much you will serve alongside the pie and mash. The NHS gives 80g as an adult fruit-or-vegetable portion and says potatoes do not count towards 5 A Day. I want to plan the vegetable serving separately from the mash, rather than counting the potato as that portion.

What can make a two-pack choice less useful?

  • Choosing two large bags without checking the freezer

    Bulk bags are less convenient when there is no suitable space for both, especially once one has been opened.

    Check the space before shopping. If it is tight, consider one larger loose bag and a smaller pack for pie night.

  • Assuming all mixed vegetables contain the same ingredients

    A standard carrot-and-pea mix offers a different combination from a medley containing broccoli and cauliflower.

    Choose by the ingredient list and the meals in which you expect to use each pack.

  • Using another pack’s cooking instructions

    Preparation methods differ between loose vegetables and microwave steam bags. Birds Eye and M&S instruct cooks to cook the checked products from frozen.

    Follow the method on the pack in hand, including its guidance on handling hot steam bags and thawed vegetables.

Which product ranges are relevant?

Birds Eye

Its frozen vegetable range includes peas-and-sweetcorn mixes and Steamfresh microwave bags.

  • Birds Eye gives separate from-frozen instructions for its peas-and-sweetcorn mix and its Steamfresh products.
  • Check the method for the particular pack: Birds Eye says its Steamfresh Super Sunshine bag should go into the microwave unopened and unpierced.

Tesco

Tesco lists 1kg own-label mixed-vegetable and farmhouse-mix bags for shoppers planning loose portions across meals.

  • The listed 1kg format gives a starting point for a two-bag freezer shop.
  • Check the ingredients and cooking instructions on the specific bag before choosing it for pie night.

Waitrose Essential

Essential Mixed Vegetables is a 1kg loose mix of carrots, peas, green beans and sweetcorn.

  • The listed mix can be portioned according to the meal.
  • An opened loose bag needs to be kept securely closed and frozen between uses.

M&S

Its listed frozen mixes include a 500g British Vegetable Medley and a 750g organic mixed-vegetable pack.

  • The British Vegetable Medley includes broccoli and cauliflower as well as peas and carrots.
  • The medley is a smaller pack than a 1kg loose bag; check how much you need for the meal and later use.

Questions about buying and cooking

Which frozen vegetables go with pie and mash?

Peas or peas and sweetcorn are straightforward choices if that is the side you want; Birds Eye suggests serving its peas-and-sweetcorn mix with mashed potato. A loose mixed-vegetable bag gives you another option if you also plan to use it in later meals.

Should I buy two loose bags or steam bags?

Choose two loose bags if you have freezer space and expect to take different amounts for several meals. Steam bags suit portioned microwave preparation; check the total pack weight and cooking instructions when deciding how many packs you need.

Can these frozen vegetables be served without cooking?

Do not serve the checked Birds Eye or M&S products uncooked: their instructions require cooking from frozen. Follow the method on the exact pack and make sure the vegetables are piping hot before serving.

Can I refreeze vegetables after they thaw?

The checked Birds Eye and M&S instructions say not to refreeze their products after thawing. Keep each pack frozen as directed and check its own storage instructions.

Does the mash count towards 5 A Day?

No. The NHS says potatoes eaten as part of a meal do not count towards 5 A Day. It gives 80g as an adult fruit-or-vegetable portion and says three heaped tablespoons of frozen carrots, peas or sweetcorn count as one portion.
