Stir Fry Ginger Beef

This came from the recipe site "Simply Recipes". I revised it a bit because the recipe calls for 2-3 serrano peppers, preferably red. I used 2 green ones but it was still way too much heat and I believe most people will find 1 quite enough. Japapenos can also be used or any pepper with heat. Also, I use any 2 steaks that are in my freezer replacing the top sirloin in the recipe below.
