Creating Sizzling Chinese Pepper Steak with Onions can be straightforward if you follow these simple steps:

1. Prepare the Beef: Slice the beef against the grain into thin strips. This helps ensure tenderness.
2. Marinate: In a bowl, combine the sliced beef with soy sauce, oyster sauce, cornstarch, sugar, sesame oil, and rice vinegar. Allow it to marinate for at least 15 minutes.
3. Heat the Oil: In a large skillet or wok, heat vegetable oil over medium-high heat until shimmering.
4. Cook the Beef: Add the marinated beef in a single layer. Sear for about 3-4 minutes until browned, then remove from the pan and set aside.
5. Cook the Vegetables: In the same pan, add the sliced onions and bell pepper. Stir-fry for 3-4 minutes, or until they start to soften.
6. Add Garlic: Stir in the minced garlic and cook for an additional minute, making sure it doesn’t burn.
7. Combine: Return the beef to the skillet with the vegetables. Stir well to combine and cook for another 2-3 minutes, allowing the flavors to meld.
8. Season: Taste the mixture and season with salt and black pepper as needed.
9. Serve: Turn off the heat and transfer everything to a sizzling platter or a hot pan.
10. Garnish: If desired, garnish with sliced green onions before serving.
