The Classic Combo Of Beef With Swiss Cheese And Sautéed Mushrooms Is The Star Of These Toasted Sub Rolls. The Juices From The Filling Soak Into The Bread On The Inside, But The Rolls Stay Perfectly Crunchy On The Outside. If You Are Looking For More Of A Philly Cheesesteak Flavor Profile, Substitute Green Bell Peppers For The Mushrooms And Use Provolone Cheese Instead Of Swiss.
