My favorite way to freeze these pizza bites is to let them come to room temperature and place them on a jelly roll pan lined with a Silpat mat. They flash freeze, and then I pop them in a freezer gallon storage bag. That way, I can enjoy them whenever I want a quick snack or a light lunch. Spritz them with water and either microwave them until heated or defrost them and pop them in a 350°F oven for about 10 minutes.
