Heat vegetable oil in a frying pan and add pork. Season with salt and pepper and cook thoroughly.
Once the meat is cooked, add onions and cabbage and stir fry.
Slide pork and vegetables to the edges of the frying pan and add Yakisoba noodles in the middle. Add water and cover, letting it steam until the water is fully evaporated. Once the noodles are loose, add seasoning packet and toss everything together until combined. Add salt and pepper to adjust the taste. Transfer to a plate and set it aside.
Clean the frying pan and remove excess water. Heat vegetable oil and pour in egg and milk mixture and make a thin omelet.
