Weekly office lunch preppers
If you batch-cook pasta sauce, soup, chilli or stew, separate 400g tins let you open one for a recipe while keeping the others in the cupboard.
Who is a multipack for?
A multipack is most useful when the number of tins matches how often you cook, rather than simply how many lunches you hope to pack.
Budget-led batch cooks
If you compare multipacks, check the displayed price per kilogram for the same tomato format and distinguish a standard price from any loyalty offer. Also consider whether you will use the pack’s full quantity.
One- or two-portion lunch cooks
If a recipe needs less than 400g of tomatoes, a smaller tin or a planned second use may be more practical than keeping part of an opened tin.
What should you check before buying?
Start with the amount each recipe uses, then choose the texture and check the instructions for anything left in an opened tin. A multipack contains cooking ingredients, not ready-packed lunches.
| Priority | What to check | Your needs |
|---|---|---|
| Pack quantity | Count the 400g tins against the amount your recipes use. A 4 × 400g pack contains 1.6kg; six- and twelve-tin packs require more cupboard space. | I cook tomato-based lunches often enough to use the unopened tins, but do not want to open more than a recipe needs. |
| Unit price | Compare the displayed price per kilogram for comparable products. Check whether an offer requires a loyalty card and whether a smaller tin better fits the recipe. | If I am buying several tins, I want to compare the amount I will actually use, not assume the largest pack offers better value. |
| Tomato format | Look for chopped, finely chopped or whole plum tomatoes as the recipe requires. Check for added herbs if you want to control the seasoning yourself. | A chunkier sauce works for some lunches; for others, I would rather start with a finer tomato base or use whole tomatoes in the recipe. |
| Opened-tin storage | Read the exact product label for transfer, refrigeration and use instructions. The reviewed Napolina and Sainsbury’s multipacks specify two days after opening, while the Mutti product description specifies five days. | When a recipe uses only part of a tin, I need a second use that fits the label’s refrigerated window. |
| Lunch preparation | Check how much tomato the recipe needs, then cook and portion the finished dish into a suitable container for work. Do not treat a tomato portion as a complete lunch count. | I want to prepare the meal at home rather than carry an opened tin to the office. |
Common buying mistakes
-
Assuming a bulk pack is automatically better value
Pack size alone does not tell you the cost for the quantity you will use, and a loyalty offer may have conditions.
Compare the current displayed price per kilogram for similar tins, keeping standard and conditional prices separate.
-
Buying four large tins for an occasional small recipe
Unopened tins can wait in the cupboard, but the remainder of an opened tin needs refrigerated storage and use within the product’s stated window.
Plan another dish that uses the remainder, or consider a smaller tin when you are cooking one portion.
Any unused remainder can become food waste if it is not used within the labelled window.
-
Treating every tomato format as interchangeable
Napolina describes its chopped tomatoes as chunky, while Mutti Polpa is described as finely chopped. A tin with herbs also changes the seasoning of a dish.
Choose the format your recipe calls for and read the ingredients if you want an unseasoned tomato base.
-
Keeping leftovers in the opened tin
The reviewed Napolina, Sainsbury’s and M&S product instructions call for opened tomatoes to be transferred to a non-metallic container and refrigerated.
Store any unused tomatoes as the exact label directs, and pack the cooked lunch separately in a suitable food container.

Questions about office lunch prep
Is a 4 × 400g multipack suitable for office lunches?
Yes, if you use the tins to cook several lunches at home or regularly use a full tin in a recipe. The pack contains 1.6kg of tomatoes; Tesco describes the Napolina pack as approximately eight 200g tomato portions, which is an ingredient estimate rather than a count of complete lunches.
Should I choose chopped or finely chopped tomatoes?
Choose according to the texture your recipe needs. Napolina describes its chopped tomatoes as chunky and suited to thick sauces, while Tesco describes Mutti Polpa as finely chopped tomato pulp in juice.
How should I store tomatoes left from an opened tin?
Transfer the remainder to a non-metallic container, cover it and refrigerate it as the product label directs. The reviewed Napolina and Sainsbury’s multipacks say to use it within two days; the M&S chopped-tomato label says three days, while the reviewed Mutti description says five days. Check the instructions on your exact tin.
What if I make only one small lunch portion at a time?
Consider a smaller tin if your recipe would leave much of a 400g tin unused. Sainsbury’s lists a 227g chopped-tomato tin with herbs as one serving; check that its basil and oregano suit your dish, or plan another use for a larger plain tin.
