1. Brush steaks with Worcestershire and sprinkle with pepper to taste; set aside. To prepare Dijon Sauce, combine mustard, mayonnaise, wine, onion, parsley and garlic; mix well.
2. Place steaks on grid. Grill over hot coals 15 minutes for medium-rare or to desired doneness, turning often. Serve with Dijon Sauce.
Note
Dijon Sauce is also great with grilled salmon and swordfish. To serve with fish, substitute white wine for the red wine and minced fresh dill for the parsley.
