DIY taco and nacho cooks
Plain tuna lets you choose the salsa, beans and other toppings yourself. Tesco uses drained tinned tuna in its taco and nacho recipes, so the recipe quantity is a useful starting point for choosing a tin.
Who each format suits
One-person shoppers avoiding leftovers
A smaller can may be easier to use in one meal. Sainsbury's labels each 80g brine can in its multipack as one serving, compared with two servings on its 145g spring-water tin. The 80g example is sold as a multipack, not as an individually sold tin.
Shoppers wanting less preparation
A prepared tuna salad can be used without assembling a plain-tuna filling. The John West Mexican-style product listed by Tesco contains tuna, vegetables, rice and beans in a spiced tomato dressing; it is a composed product rather than a plain tin.
What to check before choosing
Decide whether tuna will be a light topping, part of a shared filling or an already prepared component. That choice determines which size and ingredient list are worth checking.
| Concern | What to check | Who this matters to |
|---|---|---|
| Portion and leftovers | Compare the tin size and labelled servings with the amount of tuna in your recipe. | If I am making one light topping, I would rather use the tuna than store an opened can; about 38% of consumers put portion and leftover control first. |
| Control over the filling | Read the packing medium and ingredients to distinguish plain chunks from flavoured tuna or a composed salad. | When I am adding my own salsa, beans or chilli, I want to choose those flavours myself. About 37% of consumers make recipe flexibility their primary concern. |
| Preparation | Check whether the product is ready to eat and what it already contains; read the full allergen statement. | For a meal with little assembly time, I would choose an already prepared component over mixing a filling; roughly 25% of consumers prioritise minimal preparation. |
Common buying mistakes
-
Assuming a standard tin is one portion
Sainsbury's labels its 145g spring-water tin as two servings, but the amount needed also changes when tuna is mixed with other fillings. Tesco's taco recipe, for example, uses half a 160g tin for two people.
Check your recipe before choosing the tin, especially if tuna is the main filling rather than a topping.
-
Using a prepared salad as though it were plain tuna
A Mexican-style tuna salad may already contain beans, vegetables, rice and dressing. Adding it to a recipe that calls for plain chunks changes the ingredient mix.
Choose plain tuna when you want to build the filling yourself; read the prepared product's ingredients if you want a shortcut.
-
Overlooking allergen information
Fish is an allergen identified by the Food Standards Agency. The John West Mexican-style salad listed by Tesco also carries a precautionary statement for mustard and celery.
Read the current pack's ingredient and allergen information before serving it to anyone with a relevant allergy.
-
Keeping unused tuna in an opened can
The label information for Sainsbury's 80g brine cans directs shoppers to transfer unused tuna to a non-metallic container, refrigerate it and use it within one day.
Follow the storage directions on the tin you buy. If you expect leftovers, decide how you will use them before opening it.
Brands to consider
Sainsbury's
Its own-label examples show how labelled servings differ between small brine cans and a larger spring-water tin.
- The 145g spring-water tuna is labelled as two servings and lists skipjack tuna and spring water.
- The researched 80g brine cans come in a multipack, so that example does not meet a request for one individually sold tin.
Princes
Princes Foods lists a 145g tuna-chunks-in-spring-water format for shoppers who want to add their own seasoning.
- The stated ingredients are tuna and spring water.
- Check the exact pack size and format when shopping; Princes also has other tuna lines, including drained tuna.
Tesco
Tesco provides taco and nacho recipes using drained tinned tuna, as well as a prepared Mexican-style tuna salad.
- Its recipes help establish how much tuna to buy for a filling that includes other ingredients.
- The 220g own-label Mexican tuna salad is a prepared product, not plain tuna chunks.
John West
Its Mexican-style tuna salad is a prepared option for a meal or side, rather than a substitute for plain tuna in every recipe.
- The 220g product listed by Tesco contains tuna, vegetables, rice and beans in spiced tomato dressing.
- Its seasoning and other ingredients are already combined; check the current pack for the full allergen statement.

Questions about tuna for Mexican night
Is one 145g tuna tin enough for tacos?
It can be enough for a recipe that uses tuna alongside other fillings, but check the recipe quantity and number of servings. Sainsbury's labels its 145g spring-water tin as two servings; Tesco's taco recipe uses half a 160g tin for two people.
Can I use Mexican-style tuna salad instead of plain tuna?
Yes, when you want a prepared component rather than full control over the filling. The John West Mexican-style salad listed by Tesco already contains rice, beans, vegetables and spiced tomato dressing, so check it against the other ingredients in your dish.
What should I do with tuna left after opening a can?
Follow the directions on the product you buy. Sainsbury's label information for its 80g brine cans says to transfer unused tuna to a non-metallic container, refrigerate it and use it within one day.
What allergen information matters when choosing tuna?
Fish is an allergen identified by the Food Standards Agency. Read the current pack's full ingredient and precautionary statements, particularly for a prepared salad that contains additional ingredients.
