Ingredients for 2 servings

2 servings

Check off ingredients as you go.

Contains fish, gluten. Check the labels on packaged ingredients:

  • sourdough bread. Bread often contains soya and can contain milk, egg or sesame; check the label.
  • capers. Capers are packed in salted brine or vinegar. Rinsing them lowers the salt; the figure here is for drained capers as the record gives them.

Cooking steps

  1. Tear the sourdough bread into rough pieces and toast them in a dry pan or a hot oven until dry right through and lightly coloured. They should be hard, not soft.

  2. Chop the tomatoes into large pieces, put them in a bowl with a good pinch of salt, and leave them for 10 minutes to release their juice.

  3. Meanwhile slice the onion as thinly as you can and soak it in cold water for 10 minutes, then drain it well. Rinse the capers.

  4. Add the dried bread to the tomatoes and their juice, with the drained tuna in large flakes, the beans, the diced cucumber, the onion, the capers, the oil and the lemon juice.

  5. Turn everything over gently and leave for 10 minutes before tearing in the basil.

The useful detail

Dry the bread out properly before it goes anywhere near the tomatoes. Fresh bread dissolves into the juices within minutes; dried bread soaks them up and stays as something to chew.

Make it work for you

One serving is A large bowl, half the salad. You can switch to a smaller portion in the ingredients above; it is three quarters of this, and it contains correspondingly less energy and protein. It is an option, not a goal.

  • Tinned salmon instead of tuna

    Softer and richer, with more fat.

    Per serving: about 50 kcal more, about 5 g more protein, about 3 g more fat.

  • Black olives instead of capers

    Milder and far less sharp, with considerably more fat.

    Per serving: about 25 kcal more, about the same protein, about 3 g more fat.

  • Butter beans instead of white beans

    Larger and creamier, and they break more easily.

    Per serving: about the same energy, about the same protein, about the same fat.

Estimated nutrition

Per standard serving, calculated from the ingredients above. Nutrition changes with substitutions, brands and how much oil stays in the pan.

A salad where stale bread becomes the starch, and the tuna and beans between them take it past 30 g of protein a serving.

Show calculation notes

Each ingredient’s weight is multiplied by its USDA FoodData Central values per 100 g. The whole recipe is added up and divided by 2. Raw weights are used for meat, fish and vegetables; beans and lentils are drained weights. All of the oil is counted as eaten. Added salt is not included; sodium from stock, bread, cheese and tinned food is.

Storage and reheating

In the fridge
Best within a few hours, while the bread still has some structure. Refrigerate leftovers and eat within 24 hours.
Reheating
Not needed; this is a cold salad.

Checked against US Food and Drug Administration, Refrigerator and Freezer Storage Chart, USDA Food Safety and Inspection Service, Leftovers and Food Safety, FoodSafety.gov, Safe Minimum Internal Temperatures and FoodSafety.gov, Cold Food Storage Chart. UK guidance from the Food Standards Agency is shorter, at two days for most leftovers.
