Okonomiyaki is a Japanese savory pancake. Instead of using air bubbles to lighten the pancake, thin strips of cabbage provide levity to the cake. This is a very popular street food in Japan, and can be topped with all sorts of different ingredients, as "Okonomiyaki" roughly translates to "Grilled how you like".
Chop cabbage into thin strips.
Whisk water and egg together in a bowl and then whisk in flour, salt, and seasonings.
Fold cabbage into batter with as few folds as possible to completely work the cabbage in.
Fry meat in a pre-heated cast-iron pan or griddle on medium-high heat until brown on one side, flip, and immediately pour batter on top after flipping.
Allow to cook for 2-3 minutes and either flip the pancake, or move under a broiler to cook the top for another 2-3 minutes.
Move pancake to a serving plate meat side up and squirt tonkatsu sauce, mayonnaise, and sriracha over the top in a zig-zag pattern
Sprinkle nori on top of the sauces and the okonomiyaki is ready to serve.
