1/2 Cup balsamic vinegar
1/4 Cup soy sauce
3 Tablespoons minced garlic
2 Tablespoons honey
2 Tablespoons olive oil
2 Teaspoons ground black pepper
1 Teaspoon Worcestershire sauce
1 Teaspoon onion powder
1/2 Teaspoon salt

In a medium bowl, combine the vinegar, soy sauce, garlic, honey, olive oil, ground black pepper, Worcestershire sauce, onion powder, salt, liquid smoke and cayenne pepper.
Place steaks in a shallow, nonporous dish, and pour marinade over steaks. For optimum flavor, rub the liquid into the meat. Cover, and let marinate in the refrigerator for 24 to 48 hours.
