Prepare your teriyaki marinade (or use store bought).

Heat a cast iron skillet on high, and sear your steaks 3 minutes on each side.

Slice your steaks into bite sized pieces, and place these in the marinade. Allow the steak to marinade overnight.

Before stir frying your steak (or while if you're a good juggler), prepare your fried rice and keep warm in the oven.

Remove the steak from the marinade, reserve the marinade to use later.

Heat your wok or skillet, and add 3-4 tablespoons of oil (I like peanut).

Fry your steak in batches and keep warm in the oven.

When the steak is done, stir fry your red pepper, white onion and celery in the oil.

Mix the corn starch into the cold marinade, and then add the marinade to your wok.

Add the steak back to the wok and stir through.

Add the green onions to the wok, and stir through.

Serve over your fried rice.
