To create your very own Hunan Chicken, follow these straightforward steps:

1. Marinate Chicken: In a bowl, combine the chicken slices with soy sauce, rice vinegar, and cornstarch. Mix well to coat. Set aside for 15 minutes.

2. Prepare Vegetables: While the chicken marinates, slice the red bell pepper, green bell pepper, and onion. Mince the garlic and ginger, and set them aside.

3. Heat Oil: In a large skillet or wok, heat vegetable oil over medium-high heat.

4. Cook Chicken: Once the oil is shimmering, add the marinated chicken to the pan. Stir-fry for about 5-7 minutes or until the chicken is fully cooked and golden brown. Remove from the pan and set aside.

5. Stir-Fry Vegetables: In the same skillet, add more oil if necessary. Toss in the garlic, ginger, dried chili peppers, bell peppers, and onion. Stir-fry for 3-4 minutes until the vegetables soften but retain some crunch.

6. Combine: Return the cooked chicken to the skillet. Add chili paste and sugar, and stir-fry everything together for another 2-3 minutes, ensuring the chicken and vegetables are well coated.

7. Taste and Adjust: Sample the dish and adjust seasoning as needed. If you like it spicier, add more chili paste or dried peppers.

8. Garnish: Finally, remove the skillet from heat and garnish with fresh chopped green onions before serving.

These steps will ensure your Hunan Chicken comes out deliciously every time, bursting with flavor that will keep everyone coming back for seconds!
