Flank steak with ginger marinade

1 Flank Steak 2-3lbs trimmed of fat and silver skin

Marinade:
1/4 cup soy sauce
1/4 cup mirin, sake, or sweet sherry
1/2 cup peanut oil or vegetable
1 tablespoon sesame oil
1/4 cup finely chopped green spring onion, including tender green parts
4 cloves garlic, minced
1 tablespoon chile oil or chile paste

Score steak about 1/4" deep across the grain 3 or 4 times on both sides.

Mix marinade ingredients and let steak sit in marinade for 2 hours at room temperature or overnight in fridge. If in fridge remove 30 minutes prior to grilling.

Remove steak from marinade and pat dry grill directly over medium heat turning 2-3 times until well browned (do not cook over medium or flank steak is wasted on you)
