Cut the pork into bite-sized pieces. Mix 4 tablespoons honey, 6-8 tablespoons light soy sauce, and a pinch of cayenne pepper into a marinade. Place the pork in the marinade, turn to coat, and refrigerate for 1 hour.
Coat the pork lightly with flour. Heat peanut oil in a pan or wok over medium-high heat and fry the meat until the outer edges are crispy and well-browned, about 5-7 minutes. Remove the meat and set aside. Stir-fry the mixed vegetables in the same pan over medium-high heat for 2-3 minutes. Add the vegetable stock and bring to a boil over medium-high heat. Season with light soy sauce, 1 tablespoon oyster sauce, and a pinch of cayenne pepper. Return the pork to the pan, reduce heat to medium, and simmer for 5-8 minutes, stirring occasionally, until the vegetables are cooked through but remain firm to the bite and the pork reaches an internal temperature of 63°C (145°F).
Prepare the noodles according to the package instructions and serve with the pork and vegetable mixture.
