Millet - A number of folks have asked about millet.  It has a very similar nutritional profile to quinoa, cooks faster than rice or quinoa, costs about 1/3 the price of quinoa (a big consideration when buying for 100 people!), and is a primary grain for about 1/3 of the world's population.  In the US is sold mostly as birdseed and livestock feed, but the pearl millet variety can be found in many health . I really like both light, dry, fluffy cooked (no excess water) and the stiff porridge form (cook in excess water and let steep more).  It assumes pretty much whatever taste you add to it, so it is a very versatile grain.
