Set a small pot of water to boiling on the stovetop. This will be for your lo mein noodles.
Whisk together the dark and light soy sauce, oyster sauce, sesame oil, sugar or honey, ginger and sriracha until well combined. Set aside until ready to use.
Heat 1 teaspoon sesame oil in a large wok or pan to medium-high heat. Season the chicken with salt and pepper and stir fry 3-4 minutes, or until cooked through. Set aside.
Stir Fry the Vegetables. Heat 1 tablespoon sesame oil in the same wok to medium high heat. Add the cabbage, bell pepper, mushrooms and carrot. Stir fry for 5-6 minutes to soften.
Add the snow peas, bok choy and garlic. Cook, stirring, 2-3 more minutes to soften.
While the vegetables are cooking, boil the lo mein noodles for 3-4 minutes, or until cooked to your liking. Drain.
Stir the prepared lo mein noodles, reserved chicken and reserved lo mein sauce into the wok. Toss and stir until well coated and warmed through.
Garnish with sesame seeds and red chili flakes and serve.
