Cooking one breakfast
A smaller tin can reduce the amount left open after breakfast. Napolina lists a 227g chopped-tomato single alongside its 400g formats; check how much you intend to serve before choosing.
Who is each format for?
Cooking for two or planning another meal
A 400g tin is worth considering when both portions will be used, or when you can store a remainder. The Napolina 400g listing at Tesco describes approximately two 200g portions; the M&S 400g listing at Ocado states two servings.
Choosing by texture or salt
Chopped, whole plum and finely chopped tomatoes offer different pieces and preparation needs. If salt matters to your breakfast, compare the value per 100g on the exact tin before seasoning.
What matters when choosing?
Decide how much tomato you will use, then choose the texture; check the label before committing to a tin that may leave leftovers.
| Priority | What to check | Your needs |
|---|---|---|
| Tin size | Compare net weights and serving guidance. Napolina lists 227g and 400g chopped-tomato singles; its 400g listing at Tesco describes approximately two 200g portions. | I am cooking one breakfast and would rather not open more tomato than I expect to use, or I have a second use planned for a larger tin. |
| Texture | Check whether the tin contains chopped, whole plum or finely chopped tomatoes. Napolina describes its chopped tomatoes as chunky and its plum tomatoes as generally fleshier; Mutti describes Polpa as especially finely chopped. | Ready-cut pieces would make breakfast preparation simpler for me, or I would prefer to break up whole tomatoes to the size I want. |
| Ingredients and salt | Read the ingredients and compare salt per 100g on the exact variant. Tesco Everyday Value Chopped Tomatoes lists less than 0.01g per 100g, while Mutti lists 0.30g per 100g for Polpa. | Other parts of my breakfast may already contain salt, so I want to know what is in the tomatoes before adding seasoning. |
| Leftovers | Follow the tin’s opened-storage instructions. The examined Tesco and Napolina listings specify refrigeration and use within two days. GOV.UK advises keeping fridges between 0 and 5°C and eating cooked leftovers within two days or freezing them. | If I open a 400g tin for one breakfast, I need a practical way to store and use the remainder. |
Mistakes to avoid
-
Opening 400g for one breakfast without a second use
The 400g Napolina and M&S examples are described as about two portions or servings, so one breakfast may leave tomatoes unused.
Consider a smaller tin if that suits your portion. Otherwise, transfer and refrigerate the remainder as directed on the pack and plan when to use it.
-
Expecting every tomato tin to have the same texture
Napolina describes its chopped tomatoes as chunky and its plum tomatoes as generally fleshier; Mutti describes Polpa as especially finely chopped.
Choose chopped tomatoes for ready-cut pieces, or whole plum tomatoes if you want to break them up yourself. Check the format name when you want finer pieces.
-
Seasoning before checking the tin
Salt values differ between the cited products: Tesco Everyday Value Chopped Tomatoes lists less than 0.01g per 100g, while Mutti Polpa lists 0.30g per 100g.
Compare salt per 100g on the tin you are using, then taste the tomatoes before adding salt.
-
Using a retailer page in place of the pack
Ingredients and storage wording need to match the product in your hand. The cited M&S listing also gives inconsistent opened-storage wording in different sections.
Read the physical tin for ingredients, allergens, date marking and storage instructions, particularly when buying for someone with a dietary requirement.

Questions about tinned tomatoes
Should I choose a 227g or 400g tin for one breakfast?
Consider a 227g chopped-tomato tin if you want a smaller amount with less left open. A 400g tin is more practical when serving two or planning another use; the cited 400g Napolina and M&S examples are described as about two portions or servings.
Are chopped or plum tomatoes easier to use for a Full English?
Chopped tomatoes provide ready-cut pieces. Choose whole plum tomatoes if you prefer to crush or cut them yourself: Napolina describes its plum tomatoes as generally fleshier than its chopped tomatoes.
How should I store tomatoes left in an opened tin?
Follow the instructions on the tin. The cited Tesco and Napolina listings say to transfer unused tomatoes out of the can, cover and refrigerate them, then use them within two days. GOV.UK advises keeping fridges between 0 and 5°C; its guidance for cooked leftovers is to eat them within two days or freeze them.
What should I check if salt or allergens matter?
Read the ingredients, allergen information and salt value on the exact tin rather than relying on its format name. The cited Tesco Everyday Value chopped tomatoes list less than 0.01g salt per 100g, while Mutti Polpa lists 0.30g per 100g.
Can I use tomatoes after their best-before date?
For food marked with a best-before date, GOV.UK says the date concerns quality rather than safety. Check how the tin has been stored and look for signs of spoilage, such as mould or texture changes; do not apply best-before guidance to a product marked with a use-by date.
