Preparing Beef Stir Fry with Vegetables is straightforward. Follow these steps:

1. Marinate the Beef: In a bowl, mix the sliced beef with soy sauce, oyster sauce, and cornstarch. Allow it to sit for 5 minutes.
2. Prep the Vegetables: While the beef marinates, chop your vegetables—slice the bell pepper, julienne the carrots, and prepare the broccoli and snow peas.
3. Heat the Pan: In a large skillet or wok, heat 2 tablespoons of vegetable oil over medium-high heat.
4. Cook the Beef: Once the oil is hot, add the marinated beef and stir-fry for about 2-3 minutes until browned and cooked through. Remove the beef and set it aside.
5. Stir-Fry the Vegetables: In the same pan, add a little more oil if needed, and cook the minced garlic and ginger for 30 seconds until fragrant.
6. Add the Veggies: Toss in the broccoli, bell pepper, snow peas, and carrots. Stir-fry for another 2-3 minutes until the vegetables are bright and tender-crisp.
7. Combine: Return the cooked beef to the pan, and mix everything together. Season with salt and pepper to taste.
8. Serve: Remove from heat, serve the stir fry over cooked rice, and enjoy!
