This recipe was GREAT! I bought beef that was already cut and ready for a stir-fry, a little cheaper than the Sirloin Steak, and it's pre-cut! Also, I didn't have any Teriyaki sauce and was running out of Soy Sauce. I used the small amount of soy sauce I had(less than 1/4 cup) and 1 teaspoon of cornstarch. It still came out tasting great! If I were to make this again, I would probably use the same measurements for the soysauce and cornstarch. I was able to taste the full flavor of the beef and broccoli with a hint of flavor, rather than it being over powered. I'm looking forward to the leftovers!
