With a sharp knife, lightly score both sides of steak in a crisscross pattern. Place steak in a large ziplock bag.
In a med. bowl combine teriyaki sauce, cola, onion, garlic, red wine vinegar, oil, hot sauce and salt and pepper, whisking well. Reserve 1/2 cup of marinade. Pour remaining over steak. Refrigerate for 2 hours.
Place steak in a broiler pan or a pan with a rack in it. Broil for 10-12 mins on each side. You want this steak more done than rare. If its to rare it will be very chewy.
Let the steak rest for 10 mins.
Cut into thin slices and pour the marinated over your steak or put in a small bowl for you to dip the steak into.
