This ultimate cheese steak, an iconic sandwich in Philly, is a best-seller at Pat’s King of Steaks Restaurant. Patrons praise its thinly cut beef and crusty Italian rolls.
Pat Olivieri of Pat’s King of Steaks and his brother Harry are the inventors of the sandwich known as the Philly Cheese Steak. However, it was one of their restaurant managers who added a slice of provolone to make it a cheese sandwich. It can now be ordered with processed cheese sauce, provolone or American cheese.
In a large skillet, saute onion and, if desired, mushrooms and peppers in 3 tablespoons oil until tender. Remove and keep warm. In the same pan, saute the beef in remaining oil for 45-60 seconds or until the meat reaches desired doneness.
On each roll bottom, layer the beef, onion mixture, cheese and ketchup if desired. Replace tops.
