Quinoa, often mistakenly called a grain, has quickly become a dietary staple for many people because it contains more protein than any grain; has more calcium than milk; is high in iron, vitamins, and dietary fiber; is gluten, wheat, and cholesterol free; and is considered an excellent antioxidant. Quinoa can be used for any meal in a variety of ways, but it is largely flavorless. The Complete Idiot's Guide® Quinoa Cookbook has more than 250 recipes for every meal of the day.
