The original recipe I found was called Beef and Broccoli Stir Fry, but I added more than just Broccoli and adapted it to what ingredients I had. (Recipe adapted from Food.com)
BEEF STIR FRY
Prep Time: 20 minutes
3 tablespoons cornstarch, divided
1/2 cup water
2 tablespoons vegetable oil, divided
1/2 teaspoon garlic powder
1 lb steak cut into strips
5 cups of vegetables(approximately). I used Broccoli, carrots, and asparagus. You might also try cauliflower, water chestnuts, mushrooms, onion, etc.
1/3 cup soy sauce
2 tablespoons brown sugar
1 teaspoon paprika
First Combine 2 tablespoons cornstarch, 2 tablespoons water, and garlic powder until smooth. Add the beef and stir to coat.
Next In a large skillet (I used a wok) over medium high heat, stir fry beef with 1 tablespoon of vegetable oil (be careful not to overcook or it will become tough). Remove from pan.
Next Stir-fry broccoli and any other vegetables you'd like to add in remaining oil until tender, or about 5 minutes.
Next Combine soy sauce, brown sugar, paprika, 1 tablespoon of cornstarch and 1/2 cup of water until smooth; add to the pan.
Last Return beef to pan and stir-fry for 2 minutes.
Serve over rice.
