okay, i my family we have turkey for both thanksgiving and Christmas, which means we have to get pretty creative with the leftovers to avoid feeling like we're eating the same thing over and over and over again. this is a casserole we make that uses a little of everything you might have stealing up all the space in your refrigerator. i see no reason why you couldn't just swap in some ham and make the same meal if you didn't have turkey. it's kind of a shepherd's pie of sorts, at least that's the only thing i can think to compare it to, and it is soooo simple. simple enough, in fact, that i will skip the "recipe" and just post assembly instructions.
lightly grease a baking dish (we use a 13x9, but there are a lot of us, you could totally use an 8x8 if you are a smaller bunch) and put a thin layer of gravy in the bottom. now you just layer on stuffing, turkey, beans (or whatever veggie you have lying around), mashed potatoes and top with gravy. bake at 350 degrees for 20-30 minutes or until warmed through. remember everything is already cooked so don't go overboard here! that's it. told you it was easy.
