Wikipedia: Okonomiyaki (お好み焼き) is a Japanese savoury pancake containing a variety of ingredients. The name is derived from the word okonomi, meaning "what you like" or "what you want", and yaki meaning "grilled" or "cooked" (cf. yakitori and yakisoba). Okonomiyaki is mainly associated with Kansai or Hiroshima areas of Japan, but is widely available throughout the country. Toppings and batters tend to vary according to region.
Cooking it is easy! Mix everything really well, start up the griddle and coat it with oil, throw the ingredients down. A twist and a flip and a few minutes later...
Add sauce and toppings to decorate, snap a picture, and eat!
