Stir Fry (Marinated) Steak

Thanks to my good friend, Kim, for reminding me of this one. (Her marinated steak recipe is super-similar to this one. I had never thought to eat it just as steak itself. I've always stir-fried it with veggies, but now I know I can do it that way if the mood strikes.)
I actually haven't made this in, literally, years. It's great because you can use a cheap steak and it comes out wonderful since you're marinating it! Overnight is good, but as little as 2 hours works too.

What you need:

This makes a LOT, so freeze half of it for another time, or half the recipe.
2 pounds of boneless beef, sliced (steak, chuck roast, sirloin, any cut is fine) 

Marinade ingredients:
1 1/2 tsp. dry mustard
3/4 tsp. ginger
1/8 tsp. pepper
1/2 tsp. garlic powder
3 T. soy sauce
3 T. Worcestershire sauce
3 T. lemon juice
3 T. oil

Veggies:
3 carrots, peeled and sliced
6-8 mushrooms, sliced
2 green onions, chopped
(Any sliced veggies you like are great. Good ones to use for this are: Green peppers, zucchini, carrots, onions, mushrooms, tomatoes.)

How you make it:

Slice meat in thin strips. Mix the marinade ingredients in a bowl and add the meat. Refrigerate for 2 hours or overnight. Heat skillet on nearly high heat. Add sliced meat and marinade mixture to pan and stir fry until browned on both sides. Take out and set aside meat in a covered bowl to keep warm, keeping some of the marinade juices in the pan. Add the sliced veggies to the pan and stir fry for 5 minutes or so. Add the meat and juice back in and cover and turn heat down to low. Continue simmering for about 10 minutes or until meat is cooked through and veggies are tender. Serve over rice and enjoy! This would be great over noodles too.

On a funny side note: I kid you not, this was a recipe 30 years ago from Mr. Disturbingly Short-Shorts himself, Richard Simmons. So, I guess that makes me a toddler when my mom first came across this one. I'm glad she did...'cause it's YUM-O! Nice and healthy, so no need to break out a "Sweatin' to the Oldies" VHS afterwards! (And if you own one of those still, more power to ya.)
