Step 1

Place steaks in a glass baking dish and drizzle with Worcestershire sauce, balsamic vinegar, and olive oil. Turn to coat. Sprinkle rosemary and pepper over steaks and rub into meat. Cover and marinate for at least 1 hour. Then bring to room temperature and sprinkle with salt to taste.

Step 2

Prepare a hot fire in a charcoal or gas grill or heat a grill pan over medium-high heat.

Step 3

Place steaks on grill for about 5 to 6 minutes per side for rare and 7 to 8 minutes for medium-rare. Let steaks rest and serve with sauce.

Step 4

Combine ingredients for sauce in a small bowl.
