Turkey soup .... or more appropriately, Thanksgiving soup.
Boil turkey carcass with celery, onios, carrot and chicken stock
Add leftover turkey
Add leftover gravy
Add vegetables (whatever .. corn, green beans, etc)
Add leftover mashed potatoes
Add leftover stuffing
Season to taste with salt/pepper ...I like to use some seasoned salt and tony chachere. Bring it to a coil to incorporate all the thick stuff and then simmer away.
Makes for one amazingly flavorful soup. It is like Thanksgiving in a liquid!
