For Philadelphians, there’s no hotter debate than who serves the best cheesesteak: Pat’s King of Steaks or Geno’s Steaks. By most accounts, Pat Olivieri invented the sandwich of thinly sliced beef and onions in the 1930s; the cheese came along a decade later. Geno’s opened a few feet from Pat’s in 1966 with an almost identical menu, and the rivalry began. Today, Pat’s sandwiches have chopped steak; Geno’s have sliced.
Preheat the broiler. Heat the olive oil in a large skillet over medium heat. Add the onion and cook, stirring, until golden, about 4 minutes; season with salt and pepper. Remove the onion to a plate. Add the beef to the skillet and cook, stirring, until just starting to brown, about 8 minutes. Add a few dashes each of hot sauce and Worcestershire sauce and toss to coat.
Pile the beef and onion onto the rolls and top with cherry peppers and cheese. Place on a baking sheet and broil (open-face) until the cheese melts.
