Awesome Beef Teriyaki

Teriyaki is a Japanese cooking technique in which food (usually beef, chicken or fish), are grilled or broiled after being marinated or brushed with sauce. The word teriyaki combines two Japanese words: teri, meaning luster (referring to the glistening caramelization of the sauce), and yaki, meaning grill or broil (referring to the cooking technique).  
 
In the United States, teriyaki has come to mean any type of meat cooked by whatever method in teriyaki sauce, a salty-sweet Japanese sauce traditionally made with soy sauce, mirin or sake and sugar. So, beef teriyaki is thinly sliced beef marinated in teriyaki sauce before being cooked.
