Beef London broil marinated in red wine, garlic, rosemary, balsamic vinegar and light olive oil; then grilled to your liking.
Combine all of the ingredients together; then add the meat and the marinade to a resealable plastic bag. Place the bag in the refrigerator for at least 4 hours (you can refrigerate up to 24 hours before cooking).
When you're ready to grill your steak, take the meat out of the refrigerator at least 15 minutes prior so that it comes to room temperature. Remove the meat from the bag and discard the marinade prior to grilling and cook to your level of doneness.
