Let your chicken marinate for at least 15 minutes. 30 minutes is ideal. You can use any kind of stir fry sauce, but I used the Kikkoman brand. It's really good and you can buy it at pretty much any grocery store. I also sprinkled garlic powder, cayenne pepper and cajun seasoning on it. (Yes- I used cajun seasoning while making asian food. I'm trying to be more multi-cultural...even in my cooking.)
Chop up yo veggies. I chose carrots, green onion, and broccoli. These are my personal favorites.
