Colorful Beef Stir-Fry

Directions

1. In a small bowl, combine the first 5 ingredients. Place beef in a shallow dish; add half of the marinade. Turn to coat; cover and refrigerate for at least 2 hours. Cover and refrigerate remaining marinade.
2. In a small bowl, combine cornstarch and broth until smooth. Stir in reserved marinade; set aside. Drain beef, discarding marinade. In a large nonstick skillet or in a wok coated with cooking spray, cook beef in 1 teaspoon oil until no longer pink; drain. Remove and keep warm.
3. In the same pan, stir-fry green pepper and onion in remaining 1/2 teaspoon oil for 2 minutes. Add carrot and celery; cook 2-3 minutes longer. Add zucchini and snow peas; stir-fry for 1 minute. Stir in bean sprouts and heat through.
4. Stir broth mixture and stir into vegetable mixture. Bring to a boil; cook and stir until thickened, 1-2 minutes. Return beef to the pan; heat through. If desired, serve over rice or linguine.
