Prepare the Sauce : In a small bowl, whisk together soy sauce, oyster sauce, honey (or brown sugar), and sesame oil. Set aside.

Cook the Noodles : Cook the noodles according to the package instructions. Drain and set aside.

Stir Fry the Chicken : In a large skillet or wok, warm 1 tablespoon of vegetable oil over medium-high heat. Add the sliced chicken and cook, stirring occasionally, until it turns golden and is fully cooked, about 4-5 minutes. Remove from the pan and set aside.

Stir Fry the Vegetables : Pour the remaining tablespoon of vegetable oil into the skillet. Sauté the onion, red bell pepper, and broccoli for 2-3 minutes, or until they begin to soften. Add the minced garlic and grated ginger. Stir-fry for another 30 seconds until fragrant.

Combine and Toss : Add the cooked chicken back into the skillet, then toss in the noodles and pour the prepared sauce over everything. Mix thoroughly to ensure the chicken, noodles, and vegetables are well coated with the sauce. Stir-fry for another 2 minutes to warm everything through.

Garnish and Serve : Remove from heat and garnish with chopped spring onions and sesame seeds, if desired. Serve immediately and enjoy your delicious stir-fry noodles.
