Delicious Chicken Pot Pie

I don't have a picture of this pot pie, but it sure is the best I've ever made. And I've tried out quite a few in my cooking days... I hope you enjoy!

Ingredients:
1 cup potato, diced small
1 cup chopped onion
1 cup diced celery (I use 1 cup green beans instead)
1 cup chopped carrot
1/3 cup melted margarine
1/2 cup all-purpose flour
2 cups chicken broth
1 cup half and half (if I don't have it, I use regular milk- still works out fine)
1 tsp. salt
1/4 tsp pepper
4 cups chopped cooked chicken
1 store bought puff pastry sheet

Directions:
1. Preheat oven to 400 degrees.
2. Saute onion, celery, carrots and potatoes in butter for 10 minutes
3. Add flour to sauteed mixture, stirring well. Cook one minute stirring constantly.
4. Combine broth and half and half
5. Gradually stir into vegetable mixture.
6. Cook over medium heat stirring constantly until thickened and bubbly.
7. Stir in salt and pepper, add chicken and stir well.
8. Pour into a shallow 2 quart casserole dish and top with rolled out puff pastry sheet.
9.Cut slits to allow steam to escape.
10. Bake for 40-50 min or until pastry is golden brown and filling is bubbly and cooked through.

It's a perfect comfort food!! Enjoy!
