I made this last night. I didn't make any modifications except to use regular bread crumbs instead of panko bread crumbs. I did also half it- there was plenty for the three of us with leftovers for my lunch today. It was pretty good- DS really liked it and ate his portion willingly (which is a win). Will be making again.
