1/4 cup soy sauce
2 tablespoons rice vinegar
1/2 cup vegetable oil
1/4 cup brown sugar
1 teaspoon chopped ginger
1 teaspoon minced garlic
1 teaspoon salt
1 teaspoon pepper
Thaw flank steak completely, if frozen.
Take a large ziplock bag and place flank steak and all ingredients.
Place in refrigerator and allow steak to marinate for 2 hours or up to 2 days.
Preheat grill or broiler.
Remove steak from marinade; place marinade in a small sauce pan and simmer for 10 minutes.
Grill or broil steak until rare (135 degrees) or medium (140 degrees) and allow to rest 10 minutes before slicing.
Slice very thin against the grain of the meat.
Drizzle simmered marinade over sliced steak just before serving.
