Preheat oven to 350 F. Grease a 7 inch pie dish and set aside.
Roll out one sheet of pie dough and place in the pie dish. Crimp the edges however you'd like! With the other sheet of dough, cut out a heart, multiple little circles, or any design you'd like!
In a medium bowl, mix the (well drained) spinach, ricotta, egg and Parmesan. Pour this into pie dish and spread out. Top with the dough cut outs in whatever design you'd like.
Brush the top with milk and bake for about 30 minutes or until the top is golden brown. Let it rest on a wire rack for 10 minutes before slicing. Enjoy!
