Oh oh oh! This is soooo good!!! The only thing I would do differently next time, because there will definitely be a next time, is to tear out some of the bread from the top of the bun. It wouldn't alter the taste but it would make the fish and cabbage stand out more. This is amazing!!!!
OMG! Very good and wasabi is not overpowering, in fact I'll add more wasabi next time. My husband, fish hater, went for seconds! Enough said.
