Who is choosing?

Solo lunch cooks

If one tin needs to cover one lunch, compare 227g and 400g formats against the amount your recipe uses. With a larger tin, plan when you will use the remainder and follow the label after opening.

Cooks with a texture in mind

Choose chopped tomatoes for visible pieces, finely chopped tomatoes for smaller pieces, or whole plum tomatoes if you are willing to crush or blend them.

Shoppers comparing labels

Look at ingredients, salt per 100g and storage instructions on the tin you buy. These details can matter more to your lunch than a general description on the front of the pack.

What matters when choosing a tin?

Start with the amount you will use at lunch, then choose the texture and check the label for anything that affects the rest of your meal.

PriorityWhat to checkYour needs
Tin size Check whether the listing is for one 227g or 400g tin, or a multipack. Sainsbury’s labels the Napolina 400g tin as approximately two 200g portions. A smaller tin may suit my lunch if I have no plan for the remainder of a 400g tin.
Texture Check whether the tomatoes are chopped, finely chopped or whole plum. Whole tomatoes need crushing or blending if you want smaller pieces. For a short lunch break, I would rather choose the tomato texture before I start cooking.
Ingredients and salt Read the ingredients and compare salt on a per-100g basis. Sainsbury’s lists 0.10g salt per 100g for Napolina Chopped Tomatoes; Mutti lists 0.30g per 100g for Polpa, while M&S lists 0.02g per 100g for its Chopped Italian Tomatoes. If other ingredients in my lunch contain salt, I want to read the tin’s nutrition panel before seasoning the dish.
Leftovers Check the exact transfer, refrigeration and use-by instructions after opening. The Sainsbury’s Napolina label says to use the contents within 2 days; the M&S product page says within 3 days for its tin. When I open a 400g tin for one meal, I need a realistic plan for what is left.

What is easy to overlook?

  • Opening a 400g tin without a second use in mind

    The Sainsbury’s label describes a Napolina 400g tin as approximately two 200g portions and instructs shoppers to refrigerate the contents after opening and use them within 2 days.

    Plan another meal that uses the remainder, or consider a smaller tin when that is unlikely.

  • Treating every tomato format as interchangeable

    Napolina describes its chopped tomatoes as chunky; Mutti describes Polpa as finely cut. Whole plum tomatoes give you control over the finished pieces but take more preparation if you want them crushed.

    Choose the format to suit the sauce you intend to make and the preparation time you have.

  • Relying on the front of the tin alone

    Ingredients, salt values and after-opening instructions differ between the listed products.

    Read the current label, particularly if an ingredient, allergen or storage instruction affects your choice.

Common questions

Which tomato format works for a quick lunch sauce?

Choose chopped tomatoes if you want visible pieces, or finely chopped tomatoes if you want smaller pieces without crushing them yourself. Whole plum tomatoes let you adjust the texture, but you will need to crush or blend them for a finer sauce.

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

Follow the instructions on that tin rather than assuming every product has the same time limit. The Sainsbury’s Napolina 400g label says to empty, cover and refrigerate the contents and use them within 2 days; the M&S chopped-tomato page says to transfer them to a non-metallic container, refrigerate and eat within 3 days.

What should I compare if salt matters to my lunch?

Compare salt per 100g on the current nutrition panels. Sainsbury’s lists 0.10g per 100g for Napolina Chopped Tomatoes, Mutti lists 0.30g per 100g for Polpa, and M&S lists 0.02g per 100g for its Chopped Italian Tomatoes; check the tin you buy for its current details.

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, including when it is part of a meal or dish.
