- Jar for the dressing
Ingredients
- 250 gPuy lentils— weighed dry
- 1 (about 120 g)red onion, finely sliced
- 3 tbspred wine vinegar
- 60 gwalnuts, broken
- 4 tbspolive oil
- 2 tspDijon mustard
- 200 gcherry tomatoes, halved
- 1 large bunchflat-leaf parsley, roughly chopped
- 1bay leaf
How to make it
Put the sliced red onion in a small bowl with the vinegar and a pinch of salt and leave it there while you cook. Twenty minutes in vinegar takes the aggression out of raw onion and turns it bright pink.
Simmer the lentils in unsalted water with the bay leaf for 20–25 minutes until tender but still holding their shape. Salt them only at the end — added at the start it toughens the skins and the lentils stay hard however long you cook them.
Toast the walnuts in the dry pan for 3 minutes and tip them out of the pan immediately.
Whisk the olive oil and mustard into the onion and its vinegar to make the dressing.
Drain the lentils and tip them straight into the dressing while they are steaming hot. This is the step that matters: hot lentils absorb dressing, cold lentils are merely coated by it.
Fold in the tomatoes, walnuts and parsley, season generously and let it stand for 10 minutes before eating.

Variations
With goat's cheese
Crumble 100 g of soft goat's cheese over before serving. About 90 kcal and 6 g more protein per portion — and no longer a plant-based dish.
Packed lunch
Keeps 3 days in the fridge. Add the walnuts and parsley on the day you eat it, not before — the nuts soften and the parsley goes dark.
Coach's tip
19 g of protein in a salad that holds up in a lunchbox, with the fibre to keep you full until training. The walnuts are a third of the calories here, so halve them if you are counting closely — but do not drop the olive oil, which is what carries the mustard.
