Steak
Mushrooms
Green pepper
Onion
Cooking oil
Teriyaki sauce

Cut your steak into small pieces. Place in bowl. Pour some teriyaki sauce over it; set aside. Slice or dice onions, green peppers and mushrooms. Brown steak in just enough cooking oil to keep it from sticking. Add more teriyaki for more flavor, if desired. Add onions, green peppers, and mushrooms. Serve with rice and rolls. Beef flavored Rice-A-Roni goes well with this.
