I made these in puff pastry shells since I had them on hand, and so I don't know if they turned out quite like they should. I also thought the shells would be much bigger than they were so each one didn't hold much filling which sorta threw me off. But anyway... they tasted great! The filling was very good and I think would have been even better if I had been able to cook them a bit longer to really get melted well but since they were so small I didn't want them to burn. I used parmesan instead of romano since that is what I had and the rest I made as stated. Thanks for a great appetizer! I have to say that they did look cute though in the shells at least!
