Make a vertical slit in the middle of each Koppe Pan. Slice cabbage thinly. Slice boiled egg. Mix all the ingredients for Yakisoba Sauce in a bowl if using Homemade Yakisoba Sauce.
In a large frying pan, heat oil at medium high heat. Add cabbage, water, and Chuka Men, and then lower heat and cover. Let cook about 2 minutes until noodles soften.
When noodles get loose and soft, season with salt and pepper to taste, add Yakisoba sauce, and sitr-fry for a couple of minutes.
Place 1/2 of Yakisoba in each Koppe Pan. Top with Aonori, Benishoga, and a slice of boiled egg.
