To make the flax eggs, simply put 2 tbsp ground flax seeds (or ground chia seeds) to a small bowl, add 6 tablespoons of water and mix with a whisk. Set aside for 5 minutes.
Process all ingredients for the pie crust in a food processor until the dough crumbles but holds together.
Press the pie crust into the bottom of a 7-inch (18 cm) springform and put the springform into the refrigerator.
Vegan Apple Pie Filling
Next, make the vegan apple pie filling. You can use store-bought apple pie filling, but homemade is much better and it only takes 5 minutes to make it. Add all ingredients (except the diced apples) to a saucepan and bring the mixture to a boil. Add the diced apples and simmer for about 4-5 minutes, stirring occasionally.
Transfer half of the apple pie filling onto the pie crust and spread it evenly with a spatula. Put the springform into the refrigerator. Preheat oven to 350 degrees F (175 degrees C).
