Wheat berries are actually whole kernels of wheat. When processed to remove the bran and the germ, then ground into powder, they become white flour. If they are unprocessed, they're a whole grain. Chewy, with a hint of nuttiness, the kernels are versatile add-ins to salads, soups, and side dishes. Wheat berries need at least an hour to cook, although that time can be reduced if they've been soaked overnight.
