March 24 is National Cheesesteak Day! I do enjoy a good cheesesteak. For those who may not know, a philly cheesesteak is a sandwich made with thinly sliced, tender steak, caramelized onions and gooey provolone on a toasted hoagie roll. Now, doesn’t that just make your mouth water?! On the west coast, they have modified the cheesesteak to also include green peppers and mushrooms, but the original has none.
