My mom used to freeze apple pie filling. she'd prepare the apples for pie filling in a huge bowl, place them in a zip lock freezer bag, put it in a pie plate, then freeze, after they froze she'd take out the pie plate, but store the frozen pie fillings for later (usually holidays)
here's an hgtv link with other ideas
