Turkey Pie in a Sour Cream Crust

This crust recipe was given to me by a classmate, Bobby. It's really delicious and I love the texture.

Sour Cream Crust:
2 1/2 cups all purpose flour
1 cup butter, softened (Yes, you read that right. No need for cold butter.)
6 heaping tablespoons of sour cream
2 tsp baking powder
1 tsp salt

Turkey Filling (you can add any veggies you like):
1 cup peeled & chopped carrots
3/4 cup chopped celery
2 large potatoes, peeled and chopped
1/2 cup chopped onion
Turkey or chicken broth
1 cup milk
3 T corn starch
Rosemary, Tarragon, Sage & Thyme
Salt and Pepper

In a saucepan, cover the veggies with just enough broth. Add seasoning and salt & pepper to taste. Cook until tender. Mix in corn starch. Add milk and cook until thickened. Pour into 1/2 rolled out pie crust. Top with other 1/2 crust. Bake in preheated oven at 425ºF for 35 minutes.
