Grilled Bulgogi Flank Steak

I got this recipe from a magazine. I forgot the name of the magazine but I will find out and add a link to the website.

1 (2 lb) flank steak

Marinade:

1/2 cup soy sauce
1/4 cup packed brown sugar
1/4 cup toasted sesame oil
1/4 cup chopped green onions
2 tablespoons minced fresh garlic
1 tablespoons grated ginger root
1 teaspoon red chili flakes (I only used 1/2 teaspoon)

Place the marinade in a resealable plastic bag. Place the meat inside the bag and close it well. Squeeze the bag trying to cover the meat with the marinade. Let it rest in the refrigerator for 12 hours.

Discard the marinade. Grill the flank steak in a covered grill, 9 minutes per side or to desired doneness.

Once it is ready, remove from the grill onto a platter and cover with aluminum foil. Let it rest for 5 minutes and then slice across the grain. Serve immediately.
