Quinoa contains both fiber (2.6g per 1/2 cup) and protein. These two main nutrients can keep you from feeling hungry for a few hours. Use quinoa instead of rice and stir fry. Or try this wonderful breakfast: mix 1/2 cups of quinoa, 2/3 cups of water and 1/3 cups of orange juice and cook for 15 minutes. Add a spoonful of raisins and chopped walnuts.
