Heat 1 tablespoon vegetable oil in a large skillet over medium heat.
Add the ground pork and cook, breaking it up, until no pink remains and the meat is nicely browned (165°F). Drain excess fat if needed.
Stir in the grated ginger, shredded cabbage, and trimmed snow peas. Cook, stirring occasionally, until the cabbage is tender but not mushy — about 5–7 minutes.
Pour in the teriyaki sauce, taste, and season with salt and pepper. Simmer for 1–2 minutes to let flavors meld.
Transfer the pork-and-veg mixture to a baking dish (9x13 works well). Evenly spread the mixture.
Scatter the Chow Mein noodles over the top in a single layer.
Baking
Bake for 25–30 minutes, until the noodles are golden and crisp at the edges.
Serve hot and enjoy with optional toppings like sliced green onions and toasted sesame oil.
Notes
For a softer noodle layer, press the noodles into the top and tent with foil for part of the bake, removing foil the last 10 minutes. Optionally serve with extra sauces and vegetables.
