Kiwicha (also known as amaranth) is another Andean supergrain like quinoa - an ancient crop cultivated for thousands of years by civilizations like the Incas, but one that we are only just now rediscovering. Like quinoa, the seeds of the kiwicha (kee-wee-cha) plant are very high in protein, with a more complete compliment of amino acids than most other grains.
Kiwicha seeds are much smaller than quinoa - more the size of poppy seeds. The colorful plant is hardy enough to grow well high in the rugged Andes, an area inhospitable to conventional farming. The seeds are popped like popcorn and sold as cereal and snacks in South America.
Kiwicha is widely available (usually labeled "amaranth") in health food stores and supermarkets. Jen Hoy, About.com's guide to macrobiotic cooking, has several excellent recipes for this healthy grain on her site, such as Cinnamon Amaranth Grits and Amaranth Scallion Pancakes.
