Almost a supergrain, but not really a grain at all. As a chenopod, quinoa is closely related to species such as beets, spinach and tumbleweeds. Its leaves are also eaten as a leaf vegetable, much like amaranth, but the commercial availability of quinoa greens is currently limited.
To use in the granular form, rinse well, toast for a few minutes in a skillet, and cook as you would rice. Delicate and delicious!
