3/4 c. catsup
1/2 c. Worcestershire sauce
1/3 c. oil
1 tsp. salt
3 lb. boneless beef round steak

Combine catsup, Worcestershire sauce, oil, and salt in a small bowl. Cut steak in serving size pieces. Place steak in a snug fitting bowl or double plastic bag. Pour catsup mixture over steak. Cover or fasten, and refrigerate for 24 hours.

Remove steak from marinade. Grill until done as desired, brushing with marinade occasionally, or place on a rack in a broiler pan. Place under a preheated hot broiler, and cook until desired.
