Creating Pepper Steak with Bell Peppers and Onion is a straightforward process that yields amazing results. Let’s go through the steps:

1. Prepare the Beef: Place the sliced beef in a bowl and season it with ground black pepper and cornstarch. Mix well to coat the beef evenly.
2. Heat the Pan: In a large skillet or wok, heat the vegetable oil over medium-high heat until it’s hot.
3. Cook the Beef: Add the beef to the skillet in a single layer. Cook for 2-3 minutes, until browned, flipping occasionally. Remove the beef from the pan and set it aside.
4. Sauté Vegetables: In the same skillet, add the sliced onions and bell peppers. Stir-fry for about 3-4 minutes until they begin to soften.
5. Add Garlic: Stir in the minced garlic and cook for another minute until fragrant.
6. Combine Sauce: Mix soy sauce and oyster sauce (if using) with the beef broth or water in a small bowl. Pour this mixture into the skillet.
7. Return Beef: Add the cooked beef back into the skillet. Stir thoroughly to combine all ingredients evenly.
8. Thicken: Allow the mixture to simmer for 2-3 minutes, allowing the sauce to thicken slightly.
9. Taste and Adjust: Taste the mixture and adjust the seasoning as necessary, adding more soy sauce or black pepper if needed.
10. Serve: Remove from heat and serve immediately over cooked rice or noodles.

Following these simple steps will yield a Pepper Steak that is tender, flavorful, and simply irresistible.
