Bring 2 cups of water to a boil. Put couscous and salt in a heat-proof bowl. Pour boiling water over couscous. Stir thoroughly, then cover and set aside for about 5 minutes.
While couscous is resting, heat olive oil in a large sauté pan. Add currants, parsley, garlic and nuts. Stir and cook over medium-high heat for 2-3 minutes. Add couscous and gently mix all ingredients. Add salt and pepper to taste.
