Marinate the chicken: Stir together the soy sauce, rice wine and cornstarch until the cornstarch dissolves. Add the chicken, stir to coat and refrigerate for 10 minutes.
Prepare the sauce: Combine the black vinegar, soy sauce, hoisin sauce, sesame oil, sugar and Sichuan pepper. Stir until the sugar dissolves and set aside.
Turn on the exhaust fan. Heat a wok or large skillet over high heat, add the oil and swirl to coat. Add the dried chilies and stir-fry briefly until fragrant and darkened, without burning them. Add the chicken and stir-fry for 2 to 3 minutes to begin cooking.
Add the scallion whites, garlic and ginger and stir-fry for about 30 seconds. Add the sauce and toss to coat, then stir in the peanuts. Continue cooking until the thickest chicken pieces reach 165°F (74°C). Transfer to a clean serving plate and sprinkle with the scallion greens.
Note: May add broccoli, snow peas, carrots or mushrooms to this dish.
