County Road Cooking: Turkey Chili Sweet Potato Pie

I found a recipe for turkey chili shepard's pie out of my Rachael Ray Look & Cook book. This recipe looked and sounded SO good!! I made just a few changes...

4-5 Sweet Potatoes, peeled and chunked
6 Tbs. butter, cut into tablespoon size pieces
2 tsp. grated orange zest
1 cup sour cream
salt
pepper
1/2 tsp. nutmeg
1/2 tsp. cinnamon
1/2 cup brown sugar
2 Tbs. Olive Oil
1.5 lbs ground turkey
1 large onion, chopped
2 red fresno peppers, chopped
1 yellow bell pepper, seeded and chopped
2 cloves garlic
3 Tbs. chili powder
1/2 Tbs. paprika
1/2 Tbs. cumin
1/2 Tbs. coriander
1 tsp. crushed red pepper flakes
1/2 cup tomato paste
2 cups chicken stock
1 cup frozen corn kernals

Put the potatoes in a large pot, cover with water add salt and bring to a boil. Cook until tender.

While you are cooking the potatoes, heat a pan with the olive oil on medium-high heat. Add the turkey and brown.

While you do this, you can chop the onion, peppers and garlic.

When the turkey is browned, add onion and cook until tender (2-3 minutes). Then add peppers, garlic, spices, salt and pepper and cook for 8 minutes or so.

Then stir in the tomato paste and cook for 1 minute.

Add the chicken stock and simmer for a while longer, to thicken and combine flavors.

While the "chili" is simmering, drain the potatoes and return to the hot pot. Add the butter, orange zest, sour cream, nutmeg, cinnamon, brown sugar, salt and pepper and mash.
