Contains fish.

Cooking steps

  1. Boil the potatoes for 12 to 15 minutes, adding the green beans for the last 4 minutes. Drain them both.

  2. While the potatoes are still warm, turn them through the oil, lemon juice and parsley. Warm potatoes take up a dressing; cold ones shrug it off.

  3. Fold in the cannellini beans.

  4. Add the tuna last, in large flakes, and turn it through once only.

The useful detail

Break tuna into larger flakes to keep the bowl from becoming a mash. Stirred in hard it disappears between the potatoes and the beans, and the bowl loses its centrepiece.

Make it work for you

One serving is A 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.

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
Keeps, covered, for up to 2 days. Let it stand out of the fridge for a few minutes before eating, as the potatoes firm up when cold.
Reheating
Eaten cold or at room temperature.

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.
