Set a large skillet over medium-high heat. Once hot, add the sesame oil and the pork. Using a wooden spoon, break up the pork and cook until brown and cooked through, about 8 to 10 minutes. Season with salt and pepper.
Stir in the garlic, ginger and onion and cook until the onions are translucent, about 2 to 3 minutes. Add the carrots, cabbage, vinegar, soy sauce, and fish sauce and cook until the veggies have softened, another 2 to 3 minutes longer.
Cook the noodles according to the package directions and then drain and immediately add to the pork and vegetables and stir until evenly combined. Lower the flame to as low as it'll go to keep warm.
Pour the oil into a medium saucepan and set over medium-high heat. Once hot, add the wonton strips, a few at a time, and cook until brown and crispy. Using a slotted spoon transfer to a plate lined with paper towels, and season with salt. Continue frying the rest of the wonton strips.
To serve, divide the noodle mixture to bowls and top with crispy wontons, scallions and sesame seeds. Serve with sriracha and soy sauce on the side. Enjoy!
