Behind The Scenes At La Sagra Slices NYC Wine & Food Fest (Slideshow)

The event last night on the Pier 92 rooftop was packed with people who wanted to taste some amazing pizza and catch a glimpse of Bon Jovi.

Celebrity Cruises head chef John Suley was on hand to serve meatballs, piperade stew, toasted country bread, parmesan, and espelette.

Iron Chef Donatella Arpaia makes her meatballs veal-braised, and browns them until golden. Then she tops them off with her grandmother's secret recipe, and a hearty handful of Parmigiano-Reggiano.

Adam Richman, who has a cookbook coming out in March 2015, hosted the event, alongside Bon Jovi.
