Cooking one small supper
If an opened 400g tin would leave more than you plan to use, Sainsbury's labels its 227g chopped tomatoes as one serving. Check whether that amount fits your recipe rather than assuming every meal needs a full-size tin.
Who is each format for?
Cooking with tomatoes regularly
Separate tins in a multipack can be opened as needed across several meals. Choose a pack size you can store and expect to use, rather than buying several tins for a one-off supper.
Choosing a particular sauce texture
Napolina describes its chopped tomatoes as chunky and suited to thick sauces. Mutti describes Polpa as especially finely chopped with a consistent texture. Those descriptions help distinguish the cuts, but are the brands' own claims, not a taste test.
What should you check before choosing?
Match the tin to tonight's portion first, then consider whether its cut, ingredients and storage instructions suit the way you cook.
| Priority | What to check | Your needs |
|---|---|---|
| Amount to use | Read the tin weight and number of tins. Sainsbury's labels its 227g tin as one serving; a 4 x 400g pack contains four separate tins. | I'm making one small sauce tonight, or I cook with tomatoes often enough to use several tins. |
| Leftovers | Read the instruction on the specific product. Sainsbury's says to transfer opened contents to a non-metallic container, refrigerate and use within two days; M&S gives a three-day period for its chopped Italian tomatoes. | Will I use what remains after opening the tin within its labelled storage period? |
| Tomato cut | Check whether the product is chopped or finely chopped. Napolina describes its chopped tomatoes as chunky; Mutti describes Polpa as especially finely chopped. | For this supper, I'd rather have visible tomato pieces than a finer sauce base. |
| Ingredients and salt | Read the ingredient list for seasonings and compare salt figures on the same per 100g basis. The NHS explains that pre-packed food nutrition information is provided per 100g. | I want to season the dish myself, or compare the labels of two differently sized tins. |
| Availability | Check the relevant store or delivery listing before relying on a particular tin. Sainsbury's 400g chopped tomatoes were marked out of stock on the listing checked on 3 October 2026. | Tonight's meal depends on being able to get the tin when I need it. |
What can complicate a late-night supper?

Planning around a tin without checking availability
A product listing does not mean the tin will be obtainable for supper tonight. Sainsbury's 400g chopped tomatoes were marked out of stock when its listing was checked on 3 October 2026.
Check the store or delivery option you intend to use before settling on that product.
-
Opening more tomatoes than the meal needs
A partly used tin leaves you with contents that need prompt, product-specific storage. The checked Sainsbury's products say to transfer opened tomatoes to a non-metallic container, refrigerate and use within two days; the checked M&S product says within three days.
Consider a smaller tin for a small meal, or plan when you will use the remainder and follow its label.
-
Choosing by brand origin rather than tomato cut
Napolina describes a chunky chopped product, whereas Mutti describes Polpa as finely chopped. An origin description alone does not tell you which cut your recipe calls for.
Decide whether you want visible pieces or a finer base, then check the particular product description.

Questions about choosing and using a tin
Should I buy a multipack for one late-night supper?
A multipack makes more sense if you expect to use its separate tins for later meals and have space to keep them. For a one-off supper, choose an amount that fits the recipe rather than assuming several tins will be useful.
What tin size should I consider when cooking for one?
Sainsbury's labels its 227g chopped-tomato tin as one serving, making it worth considering for a small sauce. A 400g tin may still suit your recipe if you need the full amount or can use the remainder within its labelled storage period.
Should I choose chopped or finely chopped tomatoes?
Choose the cut that suits the sauce: chopped tomatoes retain more distinct pieces, while a finely chopped product has smaller pieces. Napolina describes its chopped tomatoes as chunky; Mutti describes Polpa as especially finely chopped.
How should I store tomatoes left after opening a tin?
Follow that product's label. The checked Sainsbury's chopped tomatoes say to transfer opened contents to a non-metallic container, refrigerate and use within two days; the checked M&S chopped Italian tomatoes specify a non-metallic container, refrigeration and use within three days.
How can I compare the salt figures on different tins?
Compare the nutrition panels on a per 100g basis, even when the tins are different sizes. The NHS explains this labelling basis; check each current product label alongside its ingredient list if salt or added seasonings matter to your recipe.
