This is the season for sprouts. Wheat berries, alfalfa, all sorts of whole beans can be had for a reasonable price. Just be sure they're food grade, and not for lawns or gardens (those might be treated with fungicide). Put a layer of seed in a jar, cover the top with a screen (can be cloth), and rinse it with water twice a day. You can eat them in a few days. When I'm green-hungry a sprout sandwich (bread, mayonnaise, and sprouts) is what I want.
