Fish burgers

A few weeks ago my parents mentioned that they might be coming through town over the weekend.  Our favorite fish mongers were having a sale on their cod burgers so I decided it would be a good time to try them out.  I made some buns, seared the burgers in my trusty cast iron pan, and put together a little sauce of mayo and onions.

My mom, who is quite a fan of fish sandwiches, claimed it was the best she'd ever eaten.
