Let the couscous swell according to the instructions on the packet. Stir well again and again so that no lumps form.
In the meantime, cut the onion into small cubes and sauté with the olive oil. Then mix the onion with the tomato paste and season with salt and pepper. Finely chop the mint and parsley, core the cucumber and cut into cubes, quarter the cocktail tomatoes and finely crumble the sheep`s cheese.
Mix everything with the couscous and season to taste again.
