This is a great way to use up leftover Bread, or bread that has slightly hardened. Many times I use the ends of sliced breads that my children haven't eaten. I refrigerate them in a bag throughout the week and by Saturday I have a loaf worth! With 7 kids to feed, nothing goes to waste...If you desire Kosher , omit the Pepperoni and use Turkey Bacon. If you wish to make it Vegetarian omit the meat all together. Buon Appetito!
