Mix marinade ingredients in a large container with a tight-fitting lid. Trim excess fat from steaks and pound with a tenderizing hammer on both sides. Cut steaks against the grain into individual-sized pieces. Place steaks in marinade, making sure all are thoroughly coated. Work marinade into meat with your hands, so each steak is fully flavored. Marinate 1-3 days, re-mixing several times.
Cook steaks on a very hot fire. Cut into slices on a angle against the grain.
Optional: Freeze leftover marinade, take the fat off, and heat in the microwave to kill off any bacteria. Serve this poured over cooked meat.
