01 - Cook the noodles according to package instructions. Drain, rinse with cold water, and set aside.
02 - In a medium bowl, toss the sliced chicken with cornstarch and 1 tbsp soy sauce until evenly coated.
03 - Heat 1 tbsp oil in a large skillet or wok over medium-high heat. Add the chicken and stir-fry until golden and just cooked through, 4–5 minutes. Remove chicken and set aside.
04 - In the same pan, add bell pepper, carrot, and snap peas. Stir-fry for 2–3 minutes until crisp-tender.
05 - Lower the heat to medium. Add garlic, ginger, and chili flakes to the pan; stir for 30 seconds until fragrant.
06 - Add all sauce ingredients (soy sauces, honey, brown sugar, rice vinegar, oyster sauce, sesame oil) and bring to a simmer.
07 - Return the chicken to the pan along with noodles. Toss everything together for 2–3 minutes until evenly coated and glossy. Garnish with scallions and sesame seeds. Serve immediately.
