Question: how to cook london broil on a holland grill?
Answer: Remove steak from marinade; discard marinade. Place steak on grid over medium, ash-covered coals; arrange onions and asparagus around steak. Grill steak, covered, 12 to 14 minutes (over medium heat on preheated gas grill, 16 to 19 minutes) for medium rare (145°F) turning occasionally. Do not overcook.
