Creating a Spicy Beef Stir-Fry is a straightforward process that you can easily follow. Here’s a step-by-step guide to help you prepare this delicious dish:

Step 1: Prepare the Beef

1. Marinate the Beef: In a bowl, combine the sliced beef with 1 tablespoon of soy sauce, cornstarch, and a pinch of salt. Mix well and let it marinate for at least 15 minutes.
2. Heat the Oil: In a large skillet or wok, heat 1 tablespoon of vegetable oil over medium-high heat.

Step 2: Cook the Beef

3. Sauté the Beef: Add the marinated beef to the skillet in a single layer. Cook for 2-3 minutes on each side until browned. Remove the beef from the skillet and set aside.

Step 3: Prepare the Vegetables

4. Stir-Fry the Vegetables: In the same skillet, add the remaining vegetable oil. Add the sliced onion, bell peppers, garlic, and ginger. Stir-fry for 3-4 minutes until the vegetables are just tender.

Step 4: Combine Ingredients

5. Add Sauces: Return the cooked beef to the skillet with the vegetables. Add the remaining soy sauce, oyster sauce, chili sauce, and sesame oil. Stir well to combine and cook for another 2-3 minutes.
