The one thing above all others (turkey sandwich running a close second) is turkey pot pie. Usually, I just add vegetables with the turkey, but this year I had so much dressing and mashed potatoes left over, I used them as well. So, inside the little pies, I put a layer of turkey, then on one side a large spoonful of the dressing and another next to it of the mashed potatoes. I then covered it with the leftover gravy (made extra specifically for this purpose) and topped it with the second pie crust. They were fabulous. One of my guests LOVED the little surprise of the mashed potato.
So now you know what I like, what's your favorite way to use the leftovers?
