Ingredients for 2 servings

2 servings

Check off ingredients as you go.

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

  • black olives. Olives are packed in brine and are salty; rinsing removes some of it.

Cooking steps

  1. Boil the potatoes whole in salted water for 15 to 18 minutes, dropping the green beans in for the last 4 minutes. Drain both together.

  2. Boil the eggs in a separate pan for 9 minutes, cool them under cold water and peel.

    Cooked when: the whites are set and the yolks are firm.

  3. Cut the warm potatoes into thick slices and put them in a large bowl with the beans, the oil and the lemon juice. Turn them over gently and leave for 5 minutes.

  4. Fold through the drained tuna in large flakes, the olives and the quartered tomatoes.

  5. Halve the eggs and set them on top.

The useful detail

Dress the potatoes while they are hot. A warm potato drinks oil and lemon juice straight in; a cold one sits in a puddle of it and tastes of nothing.

Make it work for you

One serving is A large plate, half the salad, with one egg. 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 and slightly more protein.

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

  • Capers instead of olives

    Much sharper and far less fat. Rinse them first.

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

  • Asparagus instead of green beans

    Softer and greener; give it 3 minutes rather than 4.

    Per serving: about 10 kcal less, 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 composed salad substantial enough to be dinner, where the tuna and the eggs stack to the low thirties for protein.

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
Keep covered in the fridge for 3 to 4 days, though the potatoes firm up. Take it out half an hour before eating.
Reheating
Not needed; this is served warm 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.
