Fonio is a quick-cooking ancient grain that's naturally gluten-free, has a low glycemic index, and is high in protein, fiber, minerals, and amino acids. Additionally, it has a mild, nutty flavor and a great texture that makes it an ideal substitute for rice, couscous, or other grains. It's delicious in sweet or savory applications—think grain bowls, overnight "oats," or try it served alongside curries, soups, and stews.
