Cut vegetables and meat.
Heat oil in large pan on medium high heat and cook the protein (meat/seafood)
Add onion, carrots, cabbage and cook until they're soft. While cooking the vegetables, remove yakisoba noodles from the package and run under hot water to separate the noodles.
Lower the heat to medium and add the black pepper, noodles, and yakisoba sauce. Mix all the ingredients together, making sure not to burn the ingredients in the pan.
Serve on a plate and top noodles with shredded nori and Kewpie Mayonnaise. Serve hot!
