I'm soooooo sorry it took me so long to post this...I honestly thought that I had done it. This was excellent! I had no idea what panko is, so I used homemade bread crumbs. I was worried about butterflying, because I've never done it before. So I just jumped in and did it (wasn't as bad as I thought, and still have all my fingers!) Great flavor, and oh, so tender. Very nice presentation.
