Step 1

In a small bowl, combine soy sauce, Mirin, and Worcestershire sauce.

Step 2

Bring a large pot of water to a boil. Add the noodles and cook according to the directions on the packaging. Drain in a colander, and then rinse under cold water. Set aside in the colander to drain.

Step 3

Pour the oil into a large wok set over high heat. When just starting to smoke, add the onion. Stir-fry until onion is soft, about one minute. Add the pork and cook, stirring occasionally, until it is no longer pink. Add the cabbage and carrot. Stir-fry until the cabbage is starting to soften, one to two minutes.

Step 4

Add the noodles, and stir-fry for a minute. Pour in the sauce and stir well. Stir-fry until the sauce has been absorbed, one to two minutes. Add the scallions, stir well, and then turn off the heat.

Step 5

Divide the contents between two plates, and garnish with a sprinkling of bonito flakes. Season with salt and togarashi to taste.
