Philly Cheese Steak
A cheesesteak (also known as a Philly cheesesteak, cheesesteak sandwich, cheese steak, or steak and cheese) is a sandwich prepared from thinly sliced beefsteak and melted cheese in a long hoagie bread. It is a popular regional fast food that originated in the United States city of Philadelphia, Pennsylvania.
It's a greasy sandwich so revered in its birthplace that the position required to eat it without destroying your clothing has a name: "the Philadelphia Lean." The Philly cheese steak sandwich is made with "frizzled beef," which is cut while being grilled in fat, and gets the rest of its greasy flavor from onions and cheese (American, provolone, or Cheese Whiz), all of which is laid into a long locally manufactured Amoroso bun.
Pat and Harry Olivieri are credited with creating the first cheese steaks (initially with pizza sauce — cheese supposedly came later, courtesy of one of Pat's chefs) and selling them from their south Philly hot dog stand. Pat then founded Pat's King of Steaks, which still exists today and competes for the title of greatest cheese steak in town with rival Geno's Steaks.
