Lettuce pancakes

I have this overstock of salad lettuce in my refridgerator and I didn't want to throw them out. As a household of one, who loves to buy stuff from costco, I always end up with too much vegetable I s so I have to constantly come up with things to do to them.

Today's project is lettuce pancake inspired by the japanese traditional food okonomiyaki. I topped it with caramelized onions and honey balsamic vinegar mix.
