Season the pork with salt, pepper and soy sauce and sprinkle with the katakuriko to prevent it from becoming tough.
Stir fry the onion first. Once it has been cooked slightly, add the pork.
Once the meat is cooked through, add the bean sprouts. Season with the yakiniku sauce and it's done!
Story Behind this Recipe
I think I saw it in a magazine as a recipe with pork and onions. I made it my way and added the bean sprouts to make it even more delicious.
Sprinkling the pork with the katakuriko (potato starch) makes the meat soft. The sauce is just a commercially sold yakiniku (grilled meat) sauce, so it's easy. The crispiness of the bean sprout is its best point so be sure not to over cook it.
