Ingredients
2-3 spicy chili peppers chopped
2 cloves garlic chopped
½ cup soy sauce
2 tablespoons apple cider vinegar
2 tablespoon olive oil
1 teaspoon sugar
1 teaspoon cayenne pepper
1 teaspoon dried oregano
1 teaspoon dried thyme
1 teaspoon salt
1 teaspoon black pepper
Hot sauce or sriracha to taste 1-2 tablespoons
2 pounds London Broil

Directions

Add the chili peppers, garlic, soy sauce, vinegar, olive oil, sugar and seasonings to a food processor. Process until very smooth.

Score the London Broil on both sides with a crosshatching pattern, about ¼ inch deep to allow the marinade to penetrate the meat.

Add the meat to a large baggie or into a wide dish and pour the marinade over it. Rub the marinade into the meat and cover.

Refrigerate and marinate the meat at least 6 hours, though it is best to marinade overnight for better flavor.
