FREEZE IT! Place the pies on a baking sheet and flash-freeze 45 minutes. Then cover tightly with heavy-duty foil and freeze up to 6 months. To bake, preheat the oven to 350 degrees F. Bake the foil-covered pies for 1 hour (or 35 minutes for muffin-size pies). Remove the foil and bake 30 to 50 minutes more (10 to 15 minutes for muffin size), until hot and bubbly.
