Ahhh, Pete Wells gives a shout-out to the best, dearly departed food truck on the Penn campus: Sophie’s. Their meatball subs (did I call it a meatball hoagie then? Can a hoagie even be hot? I can’t remember) were perfect. They made them to order—none of that powdered Parmesan cheese crap—in an oven in the truck. Then one day, just like that, Sophie’s was gone, and meatball subs in Philadelphia were never quite the same. Primo’s on Market Street made a pretty good one, though, as I recall.
(Also, I understand the inherent regional appeal of the cheesesteak, but I would argue that the roast pork sandwich at Tommy Dinic’s—topped with broccoli rabe and provolone—is the best sandwich in Philadelphia.)
