This sandwich is a decadent mashup of classic BBQ and a Philly cheesesteak, utilizing tender, flavorful smoked brisket instead of traditional steak. The reheated, chopped brisket, caramelized onions and peppers, and melted provolone cheese are piled high onto a toasted roll. It's a rich, intensely savory, and deeply comforting sandwich that elevates a classic with a deep, smoky barbecue flavor.
