First make the couscous: peel and dice the onion. Deseed the sweet peppers and dice. Deseed the chilli and chop finely. Remove the stalks from the parsley and chop the leaves coarsely, reserving a few whole leaves for garnish. Shred the mint leaves.
Boil the amount of water specified on the couscous packet and pour it over the couscous. Stir for 2—3 minutes
