My husband is a picky eater, but he loved this sandwich. I put a little Italian dressing on to give it a little more flavor, and we both liked that. It did stick to the cookie sheet, so the second time I tried it, I sprayed it really liberally with cooking spray and when I turned the sandwiches, put them in a different spot. That seemed to help. I could easily see trying a variety of different meats and cheeses.
