5. In a separate bowl, combine BBQ sauce, maple syrup, brown sugar, and apple cider vinegar.
6. Place your London Broil  on the grill and reduce the heat.
7. With a brush, later the broil with the glaze and then close the grill. Re-glaze the london broil every 3-5 minutes.
8. After about 10 minutes of cooking on the covered grill, flip the meat and cook for an additional 10 minutes, continuing to glaze. Remove from heat when the meat thermometer reads 135-140 Degrees fahrenheit. Allow to cool before slicing and serving.
