Thank you, Rita. This is one of those 'go to' recipes that works for all occasions. I haven't made them in a long while, last time, I did a green chile potato gratin which was good, but not as good as these.
I have unsuccessfully tried to find smoked mozzarella here. I used to buy it at TJ's and Costco, and use it on pizza. All I found was some smoked provolone and TJ's now only carries marinated mozzarella in olive oil and herbs. I haven't checked Whole Foods here yet.
