"It's got bread," Rendell told WPHT-AM. "Would you put a hoagie in the sandwich category? What I would think is the hot dog, the cheese steak, the hoagie, they're in the elite sandwich category...If you eat a hot dog without the bun, it's not a sandwich, obviously. But if you use the bun, I think that it's just a different type of sandwich, but it's still a sandwich. The bread to me would be the key."
Rendell's sentiments echoed those of comedian Hannibal Buress.
"A hot dog is a sandwich if you really think about it. It's bread, it's meat, it's toppings. It's just a different approach to the sandwich. It's not a sandwich like, classically, but it's a sandwich in spirit and it has all of the things a sandwich would have," Buress told Esquire.
