Creating the 30-Minute Beef Stir Fry with Vegetables is easy and quick. Just follow these simple steps:

1. Prep the Ingredients: Thinly slice the beef sirloin and chop the vegetables into bite-sized pieces.
2. Marinate the Beef: In a bowl, combine the beef slices with soy sauce, oyster sauce, and cornstarch. Mix well and let it marinate for about 5 minutes.
3. Heat the Oil: In a large skillet or wok, heat the vegetable oil over medium-high heat.
4. Cook the Beef: Add the marinated beef to the skillet in a single layer. Cook for 3-4 minutes until browned, stirring occasionally.
5. Add Garlic and Ginger: Stir in the minced garlic and ginger, cooking for an additional minute until fragrant.
6. Incorporate Vegetables: Add the mixed vegetables to the skillet, stirring continuously. Cook for about 5-7 minutes until the vegetables are tender yet crisp.
7. Season: Season with salt and pepper to taste. If you’d like extra sauce, feel free to add a splash more soy sauce.
8. Serve: Remove from heat and serve immediately over cooked rice or noodles.
