"London broil" can refer to several cuts of meat, some are tougher than others. I always use flank steak, not frozen, and marinate it 12 - 24 hours. This isn't to tenderize the steak, but to add flavour. I broil flank steak for about 6 to 8 minutes each side, then tented with foil for up to 20 minutes before slicing thinly across the grain. Don't slice immediately after cooking; the resting period is important. So I think you should thaw (in the refrigerator) and marinate the steak first.
