Asparagus Beef Stir-Fry

Asparagus Beef Stir-Fry

1 lb beef tenderloin, cut in strips
1 green onion
2 garlic cloves, minced
1/2 t salt
1/4 t pepper
1 T vegetable oil
1 lb fresh asparagus, trimmed and cut in 2 inch pieces
1/2 lb fresh mushrooms, sliced
1/4 c butter
1 T soy sauce
1 1/2 t lemon juice

In a wok or large skillet, stir-fry beef, onion, garlic, salt and pepper in oil for 3-5 minutes (I added all of this to the meat, but you may need a bit more oil); remove and keep warm. In the same pan, stir-fry asparagus and mushrooms in butter until asparagus is tender. Return meat to the pan. Stir in soy sauce and lemon juice and heat through. Serve with rice.
