Preheat broiler. In a bowl, combine chicken with the teriyaki sauce and let stand 10 min to marinate. Lightly spray broiler pan; arrange chicken slices in a single layer so they don't touch. Broil for 1 1/2 to 2 min on each side. Tranfer to platter. Sprinkle with scallions and sesame seeds. Serve with rice and steamed vegetables. S.C.C.U. Cookbook.
