2 tb Corn oil
1 1/2 ts Unseasoned meat tenderizer
1/4 ts Marjoram
1/4 ts Rosemary
1/4 ts Thyme

1 hour before serving combine vinegar, Worcestershire, oil, meat
tenderizer & herbs. Pierce steak on all sides with fork; pour mixture
over meat & refrigerate for 1 hour, turning once or twice. Grill or
broil 8-12 minutes on each side, basting with vinegar mixture
occasionally. To serve, carve into thin slices. NOTE: Flank steak
may be used. Score flank to keep it flat while cooking. Grill close
to heat 5 minutes on each side. Carve into thin slices, cutting
across grain.
