In a small mixing bowl, combine all the sauce ingredients.

Step 3

Heat 1 tablespoon of oil in a wok or a heavy duty skillet over high heat until smoke comes up. Add the beef and stir-fry quickly, about 1-2 minutes until the center of beef slices is slightly pink. Transfer to another plate and set aside.

Step 4

Add the remaining oil in a wok and stir-fry peppers, onion, and ginger until crisp tender, about 2-3 minutes. Add garlic and stir-fry.
