What to check before buying
Start with the number and type of lunches you are planning, then check preparation instructions and the label for the amount you would actually eat.
| Priority | What to check | Your needs |
| Pack and flavour |
Compare a fixed 4 × 400g pack with individual cans or a 3 × 400g chunky pack. Check whether every can in a multipack is the same flavour. |
I have several lunches to cover, but I would rather choose separate cans if I do not want the same flavour each time. |
| Portion size |
Read the stated serving size as well as the can size. Tesco lists Heinz Cream of Tomato Soup nutrition per half of a 400g can; double those figures if you eat the whole can. |
One can might be my lunch, so I want nutrition figures for the amount I will eat, not just the labelled serving. |
| Heating |
Check the equipment and instructions for the exact soup. Sainsbury's says to empty Heinz Chunky Big Chicken & Vegetable Soup into a covered microwaveable dish; ASDA says Campbell's condensed chicken soup needs added water before heating. |
Between lectures, I need enough time and the right bowl and utensils to prepare the soup I choose. |
| Ingredients |
Check the current ingredients and allergen declarations for each flavour. Sainsbury's labels Heinz Vegetable Soup suitable for vegetarians; ASDA lists wheat and milk for Campbell's condensed chicken soup. |
If I avoid particular ingredients, a familiar brand name or a similar-looking can is not enough to identify a suitable flavour. |
| Salt |
Compare salt for the portion you intend to eat. Tesco lists 1.1g per half-can serving of Heinz Cream of Tomato Soup; the NHS advises adults to have no more than 6g of salt a day. |
I want to compare cans on the same portion basis, especially if I would eat a full 400g can. |
Brands and retailers to compare
These references illustrate different soup formats and label checks; they do not establish that every named product is currently available.
Heinz
Tesco lists Heinz Cream of Tomato as a 4 × 400g pack, while Sainsbury's lists a 3 × 400g Chunky Big Chicken & Vegetable pack and an individual Vegetable Soup.
- The listed formats offer a choice between repeat-flavour packs and an individual vegetable can.
- Check the exact flavour and current label; Sainsbury's labels the vegetable soup suitable for vegetarians, which does not describe the chicken soup.
Sainsbury's
Sainsbury's lists its own Cream of Tomato Soup as a 4 × 400g pack.
- Four cans provide a straightforward fixed-flavour option for repeat lunches.
- The pack does not provide a choice of flavours within it.
Campbell's
ASDA lists Campbell's Condensed Cream of Chicken Soup as a 295g single can rather than a ready-to-heat multipack.
- Its condensed format is an alternative when you specifically want soup prepared with added water.
- ASDA lists wheat and milk as allergens and says it may contain egg; preparation also requires adding liquid.
M&S
M&S provides vegetarian and vegan filters within its tinned-soup range.
- The filters can help narrow down individual soups to inspect.
- Check the exact can label rather than applying a range filter to every soup; M&S instructs customers to refrigerate its opened Chunky Chicken and Vegetable Soup in an airtight container and eat it within two days.
Tesco
Tesco lists Heinz Cream of Tomato Soup in a 4 × 400g pack with nutrition information per half-can serving.
- The pack size and serving information help distinguish the number of cans from the labelled number of portions.
- Use the figures for the amount you would actually eat if a full can is your lunch.
Asda
ASDA lists Campbell's Condensed Cream of Chicken Soup as an individual 295g can.
- The listing states how to prepare the condensed soup and identifies its allergens.
- A single condensed can requires different preparation from a ready-to-heat 400g can.

Questions about lecture lunches
Does one 400g can count as one serving?
Not necessarily: Tesco lists nutrition for Heinz Cream of Tomato Soup per half-can serving. If you eat the whole 400g can, double its stated half-can figures to compare the amount you consume.
Can I microwave soup in its metal can?
No. Sainsbury's instructions for Heinz Chunky Big Chicken & Vegetable Soup say to empty it into a microwaveable dish and cover it. Follow the heating instructions for your exact product and microwave.
How should I keep soup left after opening a can?
Follow the instructions on that can. For its Chunky Chicken and Vegetable Soup, M&S says to transfer opened soup to an airtight container, refrigerate it and eat it within two days; do not assume another product has the same instruction.
How can I check a soup for vegetarian suitability or allergens?
Read the current ingredients and allergen information for the exact flavour. Sainsbury's labels Heinz Vegetable Soup suitable for vegetarians, whereas ASDA lists wheat and milk, with a possible egg warning, for Campbell's Condensed Cream of Chicken Soup.
Should I compare salt per serving or per can?
Compare salt for the amount you intend to eat. Tesco lists 1.1g per half-can serving of Heinz Cream of Tomato Soup, so a whole can contains twice that listed amount. The NHS advises adults to have no more than 6g of salt a day.
