Preheat broiler and coat broiler pan with cooking spray.
In a bowl or baking dish large enough to hold steak, combine green onions, garlic, ginger, soy sauce, honey, and rice vinegar; whisk until honey is dissolved. Marinate steak for 5 minutes on each side. Transfer steak to broiler pan and broil 5 to 6 minutes on each side to desired doneness. Remove from oven and let stand 5 minutes.
Meanwhile, pour marinade into a small saucepan and bring to a boil. Boil 3 to 5 minutes (to kill any bacteria).
Cut meat on the diagonal, across the grain, into thin slices. Drizzle with sauce.
