Who is each format for?

Weekend egg-and-tomato cooks

For eggs in tomato sauce, tomato beans or a quick pan sauce, decide whether you want visible pieces or a more even base. Napolina describes its chopped tomatoes as chunky; Mutti describes Polpa as finely cut pulp mixed with juice.

Small-household storecupboard shoppers

If breakfast uses only part of a 400g tin, the opened-storage instruction matters as much as the unopened pack size. The Sainsbury's, M&S and ASDA examples give different periods for refrigerated leftovers, so plan the next use around the tin you buy.

Ingredient- and label-first shoppers

Read the ingredient list and compare salt on the same per-100g basis. Published figures for the products discussed here range from 0.01g per 100g on ASDA Chopped Tomatoes to 0.30g per 100g on Mutti Polpa; they are not interchangeable simply because both products contain tomatoes.

What should you check before choosing?

Choose the cut of tomato for the dish first, then check the exact tin for ingredients, nutrition and what to do with any leftovers.

Priority What to check Your needs
Tomato texture Check whether the tin contains standard chopped tomatoes, finely cut pulp or whole plum tomatoes. Whole tomatoes need crushing or chopping if you want smaller pieces. I'd keep chopped tomatoes for visible pieces in a breakfast pan; for a more even sauce I'd choose finely chopped tomatoes, or crush whole ones to the texture I want.
Ingredients and salt Read the ingredients and compare salt per 100g, not across different serving sizes. ASDA lists 0.01g per 100g for its chopped tomatoes, while Mutti lists 0.30g per 100g for Polpa; check the current pack for either product. If I want to choose my own seasoning, I'll start by checking a plain tin's ingredients. If declared salt matters to me, I'll compare the figures on the products I'm considering.
Pack size and leftovers Check whether a single 400g tin or a multipack fits how often you cook. Follow the product's instructions for transferring, refrigerating and using tomatoes after opening. A single tin may suit an occasional breakfast; if I use only part of it, I need a plan for the remainder within that product's stated opened-life period.
Portion information Use the pack's serving information for the quantity you put in the dish. The NHS says 80g of canned fruit or vegetables counts as one 5 A Day portion and advises choosing canned produce in natural juice or water with no added sugar or salt where possible. When portion information is useful to me, I'll check how much tomato the meal contains rather than assume a whole tin is one serving.

What is easy to overlook?

  • Assuming every chopped tin has the same texture

    Standard chopped tomatoes and finely cut pulp can leave different-sized pieces in a breakfast sauce. Their ingredient lists and salt figures can differ too.

    Decide how much texture you want, then compare the ingredients and nutrition panel on the exact tin.

  • Giving every opened tin the same storage window

    Sainsbury's specifies use within two days for its chopped tomatoes, M&S within three days for its cited products, and ASDA within four days. Those periods apply to the named products and their stated storage instructions, not to all tinned tomatoes.

    If breakfast will leave some behind, read the tin's instructions and plan when you will use the rest.

    An unused remainder can go to waste if it is kept beyond the product's opened-life instruction.

  • Choosing a flavoured tin before deciding on seasoning

    Napolina sells garlic, herb and chilli versions alongside plain chopped tomatoes. A flavoured version sets part of the dish's seasoning before you start cooking.

    Choose plain tomatoes if you want to add those flavours yourself; check a flavoured tin's ingredients when its seasoning suits the dish.

  • Overlooking damage to the can

    Reading Borough Council advises against buying damaged cans because damage or incorrect processing may be associated with mould.

    Inspect the can before buying it, and do not use tomatoes from a can with concerning damage or visible mould.

Which brand ranges are relevant?

These brand examples show differences worth checking on individual products; a brand name alone does not tell you the cut, ingredients or storage instructions.

Napolina

Its chopped-tomato range includes plain tins and garlic, herb and chilli variants, with a 4 × 400g plain format among the pack choices.

  • Napolina describes its plain chopped tomatoes as chunky and packed in tomato juice; its published salt figure is 0.10g per 100g.
  • That texture description comes from the manufacturer, not a comparison of cooked sauces. Check the variant before choosing a flavoured tin.

Mutti

Polpa is Mutti's finely chopped pulp-and-juice option for cooks who prefer smaller tomato pieces.

  • Mutti lists tomato at 99.8% plus salt in Polpa, and describes its texture as finely cut pulp combined with juice.
  • Its published salt figure is 0.30g per 100g. Choose it for the stated format rather than assuming it has less salt than a standard chopped tin.

Tesco

Tesco Italian Chopped Tomatoes is a 400g own-label example containing chopped tomatoes in concentrated tomato juice.

  • The Tesco listing states the ingredients and gives 0.09g salt per 100g, making a per-100g label comparison possible.
  • Tesco notes that food products can be reformulated; use the current pack label for the product you buy.

Sainsbury's

Sainsbury's Chopped Tomatoes is a 400g own-label option packed in tomato juice.

  • Its published nutrition panel lists 0.07g salt per 100g.
  • The product instruction says to transfer leftovers to a non-metallic container, refrigerate and use within two days.

ASDA

ASDA Chopped Tomatoes is a 400g own-label example with tomatoes in concentrated tomato juice.

  • ASDA's listing gives the ingredients and states 0.01g salt per 100g.
  • Its opened-tin instructions call for transfer to a suitable non-metallic container, refrigeration and use within four days; check the current pack.

M&S

M&S lists both chopped Italian tomatoes and whole Italian plum tomatoes in 400g formats.

  • The chopped format keeps the pieces ready for a pan sauce; whole plum tomatoes let you crush them during cooking. M&S lists 0.02g salt per 100g for each cited product.
  • The cited products instruct users to transfer leftovers to a non-metallic container, refrigerate and eat within three days. Check the particular tin's label.

Questions about choosing and storing tomatoes

Which tomatoes should I use for eggs in tomato sauce?

Choose standard chopped tomatoes if you want visible pieces, or finely chopped tomatoes for a more even pulp-and-juice base. Whole plum tomatoes give you control over the final texture, but you will need to crush or chop them if you want smaller pieces.

How should I keep tomatoes left over from an opened tin?

Follow that tin's instructions: the cited Sainsbury's, M&S and ASDA products say to transfer leftovers to a non-metallic container and refrigerate them. Their stated use periods differ—two, three and four days respectively—so do not apply one product's deadline to another.

Do tinned tomatoes count towards 5 A Day?

Yes. The NHS says 80g of canned fruit or vegetables counts as one 5 A Day portion and advises choosing canned produce in natural juice or water with no added sugar or salt where possible. Check how much tomato you use rather than assuming the whole tin is one portion.

Do plain tomato tins have the same salt content?

No. Published per-100g figures differ across the named products: ASDA Chopped Tomatoes lists 0.01g, M&S chopped tomatoes 0.02g, Sainsbury's chopped tomatoes 0.07g, Tesco Italian Chopped Tomatoes 0.09g, Napolina chopped tomatoes 0.10g and Mutti Polpa 0.30g. Compare current labels for the exact products you are choosing.

Is the best-before date the only check a stored tin needs?

No. UK government food guidance says acceptability after a best-before date depends on the product, storage conditions and brand, and advises following the manufacturer's opened-life instructions. Inspect the unopened can too: Reading Borough Council advises avoiding damaged cans.
