For the couscous with figs, pistachios and 3-roses mixture, wash the white part of the leeks and cut into thin slices. Cut figs into small cubes. Steam the 3-roses mixture in a small saucepan with 3 tablespoons water until al dente.
Sauté leeks in hot peanut oil. Add pistachios and couscous and sauté briefly. Pour in the soup. Add figs, stir through, cover and let swell for about 10 minutes. Fold in the finished 3-roses mixture and season the couscous with figs, pistachios and 3-roses mixture with soy sauce.
