Add flour, sugar and salt to a food processor. Pulse a few times.
Add the cold cubed vegan butter and shortening. Pulse until it looks crumbly.
While the food processor is running, drizzle in 6-8 tablespoons of ice cold water. When it begins to clump together, stop. It will still be quite messy.
Dump the messy dough onto a floured surface and shape it into a ball. Roll the dough with a rolling pin. You don't want the crust too thick or too thin, about 1/4 inch thick is perfect.
Using a 2.5 inch round cookie cutter (may also use a glass or measuring cup to cut), cut out rounds of the dough.
Place the dough circles into the muffin pan, pressing the dough flat on the bottom. They don't have to be perfect and they won't be at the very top of the muffin cup area.
Once the pan (or two) are lined with the pie crust dough, place in the freezer while you make the filling. If making one pan at a time like me, place the rest of the pie crust in a ball in the refrigerator until ready to use.
