Choose a plain 400g chopped-tomato tin for a flexible base when you can plan another use for what remains. Finely chopped tomatoes suit a more even sauce; whole plum tomatoes suit a lunch you can prepare at home by crushing or blending them. Check the tin’s instructions for storing and using any leftovers, as the stated periods differ between products.
A 400g tin can provide the tomato base for two meals when you have a plan for the second portion. ASDA and Sainsbury’s describe their cited 400g tins as two servings; Tesco lists approximately two 200g portions for the cited Napolina tin.
Tomatoes can be cooked into a pasta sauce, soup, stew or bean dish at home. If you prefer a more even sauce texture, a finely chopped format is worth considering.
Chopped tomatoes leave visible pieces, finely chopped tomatoes provide a finer base, and whole plum tomatoes let you decide how much to crush or blend them during preparation.
Start with the recipe and the amount you will use, then check the exact tin’s ingredients and instructions for leftovers.
| Priority | What to check | Your needs |
|---|---|---|
| Portions | Check the tin’s net weight and serving guidance. ASDA and Sainsbury’s describe their cited 400g tins as two servings; Tesco gives approximately two 200g portions for the cited Napolina tin. | I can use the tomatoes across two lunches, or make one lunch and plan another meal for the remainder. |
| Texture | Choose chopped pieces for visible texture or finely chopped pulp for a more even base. Whole plum tomatoes can be crushed or blended during home preparation. | I want the tomato texture to fit my pasta sauce, soup or stew without adding a preparation step on a busy morning. |
| Seasoning | Read the ingredient list before choosing plain or seasoned tomatoes. ASDA lists garlic and oregano ingredients in its cited garlic tin; its label states 0.22g salt per half tin, compared with 0.03g per half tin for the cited plain ASDA tin. | For different lunch recipes, I would choose a plain base. If garlic and oregano fit this meal, a seasoned tin is an option. |
| Leftovers | Follow the exact product’s opened-storage instructions. The cited Sainsbury’s and Napolina products state two days after opening, the cited M&S product three days, and the cited ASDA plain product four days, with transfer and refrigeration instructions. | My next use for the remainder needs to fit the time stated on the tin, with access to a suitable container and fridge. |
Several cited 400g products are presented as about two servings. The tomatoes are an ingredient for a lunch recipe, not the whole packed meal.
Decide how you will use the remainder before opening the tin. If a smaller amount fits your plan, Napolina lists a 227g chopped-tomato format in its range; check the pack details before choosing it.
Without a second use, some of an opened tin may go to waste.
The cited products give different periods for using leftovers after opening, from two days for the cited Sainsbury’s and Napolina tins to four days for the cited ASDA plain tin.
Follow the label for your tin. Where instructed, transfer unused tomatoes to a covered non-metallic container and refrigerate them.
ASDA’s cited garlic-seasoned tomatoes contain garlic and oregano ingredients, so they will not serve the same purpose as a plain tomato base in every dish.
Choose the seasoned version when those flavours suit your planned lunch; otherwise check the plain version’s ingredients and add your own seasoning during preparation.

A whole-plum-tomato option for a lunch dish you cook at home. The tin is 400g, and the product description says cooking is required. After opening, transfer leftovers to a non-metallic container, refrigerate and use within two days, as its description instructs.

A peeled-plum-tomato ingredient for a lunch recipe cooked before work. This is a single 400g tin; check its pack label for serving guidance and instructions for any tomatoes left after opening.
Treat it as an ingredient for a prepared lunch, not a complete packed meal on its own. ASDA and Sainsbury’s describe their cited 400g tins as two servings, while Tesco gives approximately two 200g portions for the cited Napolina tin; plan what you will make with the tomatoes and when you will use any remainder.
Choose chopped tomatoes for visible pieces, finely chopped tomatoes for a more even base, or whole plum tomatoes if you want to crush or blend them during preparation. Napolina describes its plum tomatoes as generally fleshier than chopped tomatoes, while the cited Mutti listing describes a finely chopped pulp.
Follow the instructions on that product’s label. The cited Sainsbury’s and Napolina products state two days after opening, the cited M&S product three days, and the cited ASDA plain product four days; their instructions call for transferring leftovers from the tin and refrigerating them. Food Standards Scotland also advises checking the label for opened-food storage instructions.
Choose them when garlic and oregano fit the dish, rather than assuming they can replace a plain tomato base in every recipe. The cited ASDA garlic tin lists both ingredients; check its label if the seasoning or salt declaration matters to your choice.
No: check the food’s preparation instructions rather than assuming it is ready to eat without cooking. Food Standards Scotland advises checking whether food is ready-to-eat and cooking it where it is not; prepare the finished lunch according to the ingredients and recipe you use.
