Mastering Pepper Steak with Bell Peppers and Onion is straightforward when you follow these simple steps:

1. Prepare the Beef: In a bowl, combine the beef with soy sauce and cornstarch. Mix well and set aside for 10 minutes to marinate.

2. Heat Oil: In a large skillet or wok, heat 1 tablespoon of vegetable oil over medium-high heat.

3. Cook the Beef: Add the marinated beef to the skillet in a single layer. Cook until browned, about 2-3 minutes. Remove and set aside.

4. Cook Vegetables: In the same skillet, add the remaining tablespoon of oil. Sauté the sliced bell peppers and onion until tender, about 3-5 minutes.

5. Add Garlic: Stir in the minced garlic and ginger, cooking for an additional minute until fragrant.

6. Combine Ingredients: Return the beef to the skillet with the vegetables. Drizzle with oyster sauce, if using, and stir everything together. Season with salt and pepper.

7. Final Cook: Allow the mixture to cook together for about 2 more minutes, letting flavors meld nicely.

8. Serve: Remove from heat and serve immediately over cooked rice or noodles.
