Trim any fat from steak and dice.
In a large non-stick skillet or wok, heat oils and stir-fry

with a slotted spoon and keep warm.
Add the 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.
