Grilled Flank Steak Marinade

This is a very easy, wonderful solution for flank steak. It is a salty, savory sauce that combines tenderness with flavor. Great for teenage boys and large gatherings. So easy that I prepare in morning and grill when I get home from work! Do not substitute the sesame oil, it is essential for the flavor.
