1. Prep the pie shell. If using a frozen pie shell, allow to thaw at room temp for 10 minutes, prick the bottom and sides with a fork. Bake for 10-14 minutes until golden edges start to form.
2. Chop the vegetables. Wash asparagus, cut off woody ends and chop into 1/2-1 inch long pieces. Roughly chop spinach and sun-dried tomatoes and set to the side.
