To freeze this you can do two things, either freeze the dough ball by wrapping it in plastic then foil and storing in an air tight freezer safe container, or make it into the final product before filling and baking and freezing it like that. You still want to wrap it in plastic and try to get it into a freezer safe bag, but if it doesn't fit then wrap well with plastic and then foil. It should be good for about 6 months if wrapped well.
