Creating Sizzling Chinese Pepper Steak with Onions is straightforward when you follow these steps:

1. Prepare the Steak: Thinly slice the flank steak against the grain. This ensures tenderness in every bite.

2. Marinate the Steak: In a bowl, combine the sliced steak with soy sauce, cornstarch, garlic, and ginger. Mix well and let it marinate for about 10 minutes for enhanced flavor.

3. Heat Oil: In a large skillet or wok, heat the vegetable oil over high heat until it’s shimmering.

4. Cook the Steak: Add the marinated steak to the hot skillet. Stir-fry for about 5 minutes until it’s browned and cooked through.

5. Add Vegetables: Toss in the sliced onions and bell peppers. Sizzle them together for another 5 minutes until the vegetables are tender-crisp.

6. Season: Drizzle the sesame oil over the mixture. Season with salt and pepper to taste, adjusting as necessary.

7. Serve Immediately: Remove from heat and serve while sizzling hot.

By following these steps, you’ll create a flavorful dish that’s sure to please anyone at your table.
