Call them calzones, or pocket sandwiches, or pizza pockets, or piroshki. They're quick meals, portable meals that are so handy in the summertime.
My daughter, Debbie, got me started on these. She would make 30 to 40 at a time from pizza fillings to ham and cheese, bake them, and put them in the freezer.
Some she would pull from the freezer and put them in the microwave when the kids needed a snack. Some she would save for a sit-down meal.
