The last time I was in New York City, my son and his family and I had dinner at a well known restaurant called Trattoria Dell'Arte. I ordered an entree from the dinner menu called "chicken pepperoni parmigiana, burrata mozzarella" (the menu featuring this dish is at http://www.trattoriadellarte.com/menus/Tratt_BRUNCH.pdf
). I did not know what to expect, but what I got looked like the photo shown below except that my dish was almost perfectly round and it covered the entire dinner plate and looked just like a pepperoni pizza. Apparently the chicken pieces (maybe one or more) were pounded thin and formed into a pizza sized skin. The dish was terrific, and I plan to have it again the next time I am in NYC.
