Cook the noodles according to package instructions. Drain and set aside.
Blanch the vegetables (such as bok choy or other leafy greens) until just tender. Set aside.
Heat a drizzle of oil in a pan over medium heat.
Add the minced garlic and sauté for about 30 seconds, or until fragrant.
Add the ground pork and cook until it's nearly browned.
Stir in the light soy sauce, dark soy sauce, Shaoxing wine, doubanjiang, and five spice powder.
Continue cooking for another 6–8 minutes, or until the pork is fully cooked and flavorful.
In a mixing bowl, combine sesame paste, light soy sauce, dark soy sauce, rice vinegar, chili oil, ground Sichuan peppercorn (if using), and hot chicken broth.
Stir well until the sauce is smooth and fully combined.
Place cooked noodles into a bowl.
Pour in the sauce and toss the noodles until evenly coated.
Top with the ground pork mixture, blanched vegetables, peanuts, and preserved mustard greens (sui mi ya cai).
Drizzle with extra chili oil, if desired.
Serve and enjoy!
