Place the couscous grains into a bowl and pour over the hot chicken stock. Cover the bowl and leave couscous to soak the stock for 15 minutes or until tender.
Meanwhile, toast the pine nuts in a dry frying pan for 3 minutes, shaking the pan from time to time. Set aside.
Run a fork through the couscous to break up the grains and add olive oil, black olives, tomatoes, toasted pine nuts and herbs.
