Yaki Udon Stir-Fry

You can use very simple vegetables for this classic Japanese stir-fry, such as cabbage, onion and carrots, or add some bacon, chicken or prawns. The real stars of this noodle dish are the thick chewy noodles and zingy sauce. Soy, mirin and tonkatsu sauce are the key ingredients for yaki udon or yaki soba. Tonkatsu is sold under a popular brand name of Bull-Dog sauce and tastes like English HP sauce.
