Mix the marinade ingredients. Slice the steak into pieces about 2" long and
½" wide and toss with the marinade until the meat is evenly coated. Allow to sit in
fridge for at least ½ hour and up to 1 day.
Mix the sauce ingredients and set aside.
Heat one tablespoon of the oil in wok over high heat. Add beef slices to just cover wok
bottom (about 1/3 of the steak) and brown approximately one minute on each side.
Remove beef and set aside. Repeat until all beef is browned.
In 2 tablespoons oil stir fry the ginger and garlic for about 30 seconds then add the
scallions, chiles and mushrooms. Continue to stir fry for 2-3 minutes. Add the sauce and
allow to come to a boil. Mix the cornstarch and water and add to sauce to thicken. Add the
steak and the broccoli and allow to heat through for 1-2 minutes.
Serve over rice.
