Focaccia is very versatile. It can be served as an appetizer, as bread accompanying a main course, or as a whole meal all by itself. Sliced horizontally and filled with mortadella or other deli meats, it makes an amazing sandwich. If you have focaccia that is a day or two old, cut it up and make a Panzanella salad. Put your favorite pizza toppings on it for one of the best pizzas you will ever eat!
