Combine garlic, vinegar, soy sauce, oil and hoisin sauce in a large bowl; add steak. Allow to marinate in the refrigerator for 2 to 4 hours or overnight. Remove steak to plate; reserve marinade.
Preheat grill or broiler. Grill or broil steak for 8 minutes on each side for medium or longer until desired doneness. Remove and slice steak into thin strips. Meanwhile, pour reserved marinade into a small saucepan. Bring to a boil; cook 1 minute more, stirring occasionally.
To serve, place 2 cups greens on each of 4 plates. Top each with about 3 ounces of steak, ¼ cup of oranges and 1 heaping tablespoon of noodles; drizzle each with about 1½ tablespoons of cooked and cooled marinade.
Notes
Be sure to boil the marinade for at least one minute, to kill any bacteria that may have come from contact with the raw meat. You can also add ginger (1/2-1 tsp) and red pepper (to taste) flakes to the marinade if you wish.
