Start by combining sliced pork with soy sauce, minced garlic, and grated ginger in a bowl. Allow the mixture to marinate for at least 10 minutes.

Bring a large pot of salted water to a rolling boil. Add thick chow mein or lo mein noodles and cook according to package instructions until al dente, typically about 5-7 minutes. Drain and rinse with cold water.

Heat a large pan or wok over high heat and add oil. Once shimmering, add the marinated pork and stir-fry for about 3-4 minutes until browned and cooked through. Remove from the pan.

In the same pan, add more oil if necessary, and toss in chopped cabbage, sliced mushrooms, and chopped green onions. Stir-fry for about 4-5 minutes until tender yet still crisp.

Return the cooked pork to the pan with the sautéed vegetables. Add the drained noodles and pour in a splash of soy sauce, tossing everything together for an additional 2-3 minutes.

Transfer the Shanghai Fried Noodles to plates or a serving platter, garnish with additional sliced green onions or sesame seeds, and serve.
