Here's a marinade that adds flavor and tenderness to lean top sirloin.
- In an 8-cup measure, whisk together balsamic vinegar, soy sauce, garlic, honey, olive oil, pepper, Worcestershire, onion, salt (if desired), and cayenne.
- Place steaks in a shallow glass dish and cover with the marinade. Turn to coat both sides well. Cover and marinate in refrigerator for up to two days.
- Preheat grill to medium-high heat. Lightly coat the grill grate with canola cooking spray or oil. Add steaks and grill 5-7 minutes per side, depending on the thickness of the steak and the desired doneness. Throw away any leftover marinade (because it has raw meat juices in it).
