Next, add the bell pepper to the pan. Sear them over medium-high heat until they are still slightly crisp with a beautiful char on the outside. You may have to adjust the heat if it's too low or too high. Then remove the bell peppers.
½ red bell pepper, ½ green bell pepper
Add the marinated chicken thigh pieces to the pan. Sauté over medium-high heat until they are nicely colored on the outside and cooked through. Then remove the chicken from the pan.
Lastly, sauté the green onions, garlic cloves, ginger, and dried chilies over medium-low heat until fragrant. Make sure the ingredients don't burn and adjust the heat as needed.
3 green onions, 3 garlic cloves, ½ teaspoon minced ginger, 5 dried chilies
Now add back the chicken, peanuts, and bell peppers. Give the sauce a quick stir and add it to the pan. Season with ground Sichuan pepper and white pepper. Then sauté until the sauce thickens.
