What this plate gives you
Canned tuna in water is the leanest protein in the library, about 25 g per 100 g for almost no fat, and 120 g of it gives most of this salad’s 43 g. The kidney beans add 10 g of protein and most of the 10 g of fibre, a third of a 2,000-calorie day’s 28 g. At 449 calories it is a little under a quarter of that day. The only fat is the olive oil, so this is a lean lunch from the cupboard.
Swaps
- Cannellini or butter beans for the kidney beans: the same numbers, a softer bean.
- Canned salmon for the tuna: a little more fat and calories.
- Leave out the bread: 80 calories fewer.
Keeping it
The tuna and beans dressed in oil keep for two days in the fridge; add the leaves and tomatoes when you eat.
