Blueberries are more frequently available at grocery stores year-round, so you can have this anytime. For a more adventurous recipe, add a mixture of berries to this or use a different berry all together.
Preheat oven to 350°F (175°C). If using pre-packaged pie crusts, remove them from packaging and place on a lightly floured surface. Roll homemade or store bought bottom crust, placing the pie crust in a 9” pie plate. Roll second crust and prepare it for placement on top of pie. Mix filling by combining sugar, cornstarch, and cinnamon together in a medium bowl. Drizzle lemon juice over blueberries in a separate bowl and then toss with the sugar mixture and vegan butter. Add berries to pie plate with bottom crust and cover with top crust. Top the crust with 2-4 butter slices and a sprinkle of sugar, if desired. Bake for 45 minutes or until bubbly and golden brown. Remove and cool.
