This is a delicious appetizer for entertaining, or a great snack to accompany a pre-dinner glass of wine. Note that the flatbread recipe makes 4 flatbreads. Extra flatbreads can be wrapped and frozen. (Flatbreads make a great, quick pizza base, as well!) The topping ingredient amounts are for one flatbread. Double/triple as necessary. Bacon can be substituted for the pancetta. Pear would also be a nice substitute for the apple.
