I am doing the same thing today!I use turkey soup or chicken soup base for more flavor. Pick the carcass and add the meat to your soup. I add a whole onion, chopped carrots, celery, and diced potatoes. I also make Bisquick dumplings but am opting for noodles today. You make those separate and add them to the soup at the end. Cooking time is until your veggies are fork tender. I use a huge stock pot. I sometimes add left over stuffing too at the end. It's yummy!
Last night I made turkey shepherds pie. I made my own gravy because we were out by browning butter and flour and adding water along with some turkey base. I added mixed veggies and some turkey. I layered stuffing in a casserole dish, put the meat and gravy mixture over that and put the leftover potatoes over that. I topped that with some leftover butter and baked at 350 for about 25 minutes.
