Heat a very large skillet over medium-high heat and cook and crumble the ground pork. Add the garlic and ginger and cook for 1 minute, until fragrant. Add the onion, cabbage, and carrots and cook until soft and lightly caramelized. Season with soy sauce to taste.
When ready to serve, pile the stir-fried mixture over the cooked noodles or rice. Garnish with green onions, cilantro, chopped peanuts, and desired sauce.
For cilantro sriracha mayo, stir everything together and serve over rice or noodle bowls, on sandwiches, or on salads.
