Follow these simple steps to create your own delicious Hunan Chicken:

1. Prepare Chicken: Slice the boneless chicken breast into thin strips. Season with salt, pepper, and cornstarch, and set aside.

2. Heat Oil: In a large pan or wok, heat the vegetable oil over medium-high heat until shimmering.

3. Cook Chilies: Add dried red chilies to the hot oil and cook for about 30 seconds until fragrant. Be careful not to burn them.

4. Add Chicken: Quickly add the seasoned chicken strips to the pan. Stir-fry for about 5-7 minutes until the chicken is golden brown and cooked through. Remove chicken and set aside.

5. Sauté Vegetables: In the same pan, add sliced bell pepper, onion, garlic, and ginger. Stir-fry for about 3-4 minutes until the vegetables are tender-crisp.

6. Combine Sauces: In a bowl, combine soy sauce, rice vinegar, hoisin sauce, sesame oil, and water. Mix well.

7. Return Chicken: Add the cooked chicken back into the pan with the sautéed vegetables.

8. Add Sauce: Pour the sauce mixture over the chicken and vegetables. Stir well to coat everything evenly.

9. Cook Together: Allow to simmer for about 2-3 minutes, stirring occasionally until the sauce thickens slightly.

10. Garnish and Serve: Once done, garnish with chopped green onions before serving.
