Mmmmmm.... Shepards Pie!

I am in love with this Shepard's Pie recipe. Its fantastic, and all the boys gobbled it up! I have been on track now for 3 weeks and am down 5 pounds. I am pretty happy with it, but I need to make sure I am keeping up my momentum, or I will gain that back REALLY quickly. So, here is my recipe...
1 large sweet potato
1 large potato
1/4 cup fat free milk
1.25 lb ground turkey
2 tbsp all purpose flower
1/4 cup tomato paste
1 1/4 cup beef broth
1 small onion (choppped)
2 tsp olive oil
1/4 tsp thyme
salt and pepper to taste on potatoes and turkey

Peel and cube sweet potato, cube regular potato. Put in a sauce pan and cover with water. Bring water to a boil then bring it down to a simmer and cook until fork tender. Drain add milk, salt, pepper and mash. Set aside
Preheat oven to 425
Meanwhile heat oil in pan, add onions and cook until golden. Add turkey and cook until browned.
Add flower and mix in until absorbed. Then add broth and tomato paste. Simmer until slightly thickened.
Spray 2 quart baking dish with non stick spray. Add turkey mixture and top with potatoes. Bake for 15 minutes or until warmed through.
Yeilds 6 servings...

The best thing about this is that its only 4 points!
Enjoy :)
