Begin by trimming and slicing the pork into thin strips. In a bowl, combine the pork with your chosen marinade ingredients and let it soak for at least 15 minutes.

Bring a large pot of water to a boil over high heat. Once boiling, add the thick, chewy noodles and cook according to the package instructions, typically for about 8-10 minutes.

In a large pan or wok, heat a tablespoon of oil over medium-high heat. Add the marinated pork and stir-fry for about 5-7 minutes until golden brown.

Add the cabbage, mushrooms, and chopped green onions. Stir-fry for approximately 3-5 minutes until tender.

Gently fold the cooked noodles into the stir-fried mixture, and drizzle the umami-rich sauce over everything, stirring continuously for about 2-3 minutes.

Remove the pan from the heat and serve your Shanghai Fried Noodles hot, garnishing with additional green onions if desired.
