In a ziplock bag, combine grill seasoning, dark soy, honey, hot pepper flakes, garlic, sesame oil, scallions and a drizzle of vegetable oil. Put the steak in the marinade bag. Let sit for a few hours.

Preheat grill stove top grill pan or outdoor grill to medium high. When the grill pan or grill is screaming hot, add meat and cook 5 minutes on each side for medium rare, 7 to 8 minutes on each side for medium well doneness.

To serve, let meat rest 5 minutes for juices to redistribute. Thinly slice the meat on a heavy angle against the grain (the lines in the meat).
