With a bit of your own ingenuity, this can be great. I used Pillsbury flat pie crust. I also couldn't find frozen apples anywhere so I made my own. I cut up one of every kind of apple that I could find and coated them in cinnamon and froze them overnight. Then I partially thawed them and put them in the recipe. Also, I had to bake the crust for way longer than 20 minutes. I covered the top edges of crust once they were brown (20 min) and then baked for 5 minute intervals for another 20-25 minutes. It was absolutely delicious. Lots of compliments at thanksgiving. Plus I added cinnamon sugar on top instead of regular sugar.
