Artisanal Ricotta Meatball Sliders at Macaroni Grill
The classic meatball sub has been around for ages but "Artisanal Ricotta Meatball" sandwiches? This could only come from a collision of several trends. The Macaroni Grill does a "ricotta meatball" that's served on a buttery roll with spicy arrabiata sauce, mozzarella and Parmesan.
Chef ripped off: Joey Campanaro
Joey Campanaro made gourmet meatball sliders "a thing" in the late aughts by putting them on the menu at his trendy Little Owl restaurant in NYC's West Village. Made with a combo of ground veal, pork and beef, fennel, panko breadcrumbs and pecorino Romano cheese, they remain on the menu to this day, possibly inspiring the meatball craze of the last several years (see: The Meatball Shop, and others).
