Pour 1⁄2 l boiling salted water over the couscous. Cover and let it swell for at least 10 minutes. Chop the almonds and roast them in a pan without fat until golden brown. Wash or clean and dice the cucumber and tomatoes. Wash parsley, shake dry and chop.
Wash lemons hot, grate dry, grate peel thinly. Squeeze the lemons. Mix juice, lemon peel, salt, pepper and oil.
Loosen the couscous with a fork. Fold in dressing and prepared ingredients. Season to taste with salt and pepper.
Pour salt water over the couscous in a wide bowl so that all the grains are covered and swell evenly.
