Spicy Beef Stir-Fry

Instructions

1. 1

   In a large bowl, combine the beef strips with garlic powder, onion powder, salt, and pepper. Mix well to coat the beef evenly.

   Heat a large skillet or wok over medium-high heat. Add the beef strips and cook until browned, about 5-7 minutes.

3. 3

   Add the mixed vegetables to the skillet and stir-fry for another 3-4 minutes until the vegetables are tender-crisp.

4. 4

   In a small bowl, mix together the ketchup, mustard, Worcestershire sauce, and hot pepper flakes.

5. 5

   Pour the sauce over the beef and vegetables in the skillet. Stir well to combine and cook for an additional 2-3 minutes until the sauce is heated through.

6. 6

   Serve the spicy beef stir-fry hot, garnished with additional pepper flakes if desired.
