Prepare the Chicken: Cut the chicken breast into bite-sized pieces. In a bowl, mix soy sauce, honey, minced garlic, and grated ginger. Add chicken pieces to marinade for at least 15 minutes.

Cook the Noodles: Boil water in a large pot, add noodles, and cook according to package instructions (about 4-6 minutes). Drain and rinse under cold water.

Sear the Chicken: Heat oil in a skillet over medium-high heat. Cook marinated chicken for about 5-7 minutes until golden brown and cooked through.

Add the Vegetables: Stir-fry bell peppers, carrots, and broccoli in the skillet for 2-3 minutes until tender-crisp.

Combine Everything: Add cooked noodles to the skillet with chicken and vegetables. Pour over remaining marinade and mix thoroughly for 2-3 minutes.

Serve and Garnish: Plate servings and sprinkle with toasted sesame seeds and sliced green onions. Serve immediately.
