01 - In a mixing bowl, combine the sliced chicken breast with soy sauce, Shaoxing wine, and cornstarch. Toss until evenly coated and let rest for 10 minutes.
02 - In a separate bowl, whisk together the soy sauce, oyster sauce, rice vinegar, sugar, chili paste, and chicken stock. Set aside, keeping the cornstarch slurry separate.
03 - Heat 1 tablespoon of vegetable oil in a wok or large skillet over high heat. Add the marinated chicken in a single layer and stir-fry for 3–4 minutes until golden and cooked through. Transfer to a plate and set aside.
04 - Add another tablespoon of oil to the wok. Toss in the minced garlic, ginger, and spring onions. Stir-fry for about 30 seconds until fragrant.
05 - Add the red and green bell peppers, broccoli florets, snow peas, and carrot to the wok. Stir-fry for 2–3 minutes until the vegetables are crisp-tender.
06 - Return the cooked chicken to the wok and pour in the prepared sauce. Toss everything together, then drizzle in the cornstarch slurry. Stir-fry for 1–2 minutes until the sauce thickens and glossy coats all ingredients.
07 - Transfer to a serving dish and serve immediately alongside steamed jasmine or brown rice.
