okonomiyaki: savoury Japanese pancakes, any way you like them!

This will be a quick post, much like the dish, which can be thrown together in a matter of minutes.

The only ingredients that I would say are standard for this recipe are flour, egg, and chopped cabbage; after that, you can go nuts throwing in leftover vegetables, pieces of meat, seafood, etc., and if you want it to taste Japanese, at least one ingredient with a Japanese flavour (such as dashi instead of water, bonito shavings (katsuobushi), or nori flakes). These items are super cheap in Japan, and can often be found in Chinese or other Asian supermarkets.
