Cut the tempeh into chunks. Place the tempeh and sliced onion in a deep dish and pour the barbecue sauce over it. Marinate in refrigerator for at least one hour. Preheat oven to 350 degrees F and bake the tempeh for 30 minutes with a cover. The tempeh can also be grilled, basting frequently with the barbecue sauce and cooking until browned and heated through.
