Philadelphia Roast Pork Sandwiches
The Philadelphia roast pork sandwich combines roasted pork with melty provolone cheese and broccoli rabe (or sometimes spinach) for a seriously satisfying bite. For this version, we sautéed broccoli rabe with plenty of garlic and some crushed red pepper flakes, and finished it with fresh lemon juice. Its bitterness and brightness balances the fattiness of the pork, which is incredibly tender and buttery with a flavorful crust. Letting the pork sit at room temperature for an hour while the oven preheats helps ensure it cooks evenly. Roasting it initially at 450°F and then lowering the oven temperature crisps and renders the fat on top, and then slowly cooks the meat. The provolone brings sharpness and helps keep the bottom of the roll from getting too soggy, and the mayo — which has a punch of acidity from pickled pepperoncini and its brine — is the finishing touch.
