These classic Philadelphia-style pork sandwiches get a level up with juicy marinated and grilled pork tenderloin and freshly charred broccolini. Paired with a zingy pepperoncini mayo and a generous layer of melted provolone on top of a hearty hoagie roll, this sandwich is a flavor powerhouse.This recipe was created by our partners Sarah and Zach of Hangry in Love who made the dish on our Performance Series™ Amplifire™ 4-Burner Gas Grill, but you can make it on your grill or smoker.
