If you want a good introduction to whole grains, this dish is it! Once cooked, the wheat becomes roly-poly and turns a beautiful warm color, and the rye puffs up and turns a lovely shade of brown. The wild rice bursts open, releasing an irresistible earthy flavor, and revealing a cream-colored interior. You can also add some barley, for extra sweetness, and, of course, the cashews provide terrific crunch. Prepare to chew! And consider using the leftovers as your whole-grain cereal for breakfast.
