I found this recipe in a Patchwork Potluck Cookbook last year. Since I love blueberries, I thought I would try this delicious pie. This is a delicious pie that is great to make anytime of the year. It is a refreshing dessert in the summer when you don't want to heat up the kitchen. I have used the Mixed Berry Pie Filling as well for a different taste. This pie is so good that it is usually gone in one night.
