Ingredients
1 lb London Broil
1 Tbsp Spicy Brown Mustard
1/2 cup Red Onion, finely chopped
1/4 cup Extra Virgin Olive Oil
1/8 cup Balsamic Vinegar
4 cloves Garlic, smashed and roughly chopped
1 tsp Black Pepper
1 tsp Salt
Preparation
Whisk olive oil, balsamic vinegar, red onion, garlic, mustard, salt, and pepper together in a mixing bowl.
Place London broil in a ziplock bag or baking dish and cover with the marinade up to 24 hours prior to cooking.
Preheat grill to high heat.
Grill London broil on high for 4-5 minutes for the first side.
Flip, reduce heat to medium-high, and grill for another 5-6 minutes.
Remove from heat, allow to rest 5 minutes, then slice thinly and serve.
London broil tends to be a tougher cut of meat, being that it is so lean. We recommend allowing the meat to marinate for up to 24 hours to help tenderize the steak before cooking.
