Trim any fat from steak and dice. In a large non-stick skillet or wok, heat oils and stir-fry meat over high heat 1 minute. Stir in soy sauce. Remove meat with a slotted spoon and keep warm. Add celery, onions and broth to the skillet. Bring to a boil, reduce heat and cook 5 minutes. Add bean sprouts. Cook 3 minutes more, then return meat and stir to heat. Serve with Confetti Rice and Sesame Spinach Salad.
