We don't do Thanksgiving here, but the Christmas leftovers are pretty easy to use up. We share a lot between our two families and we will pack some to take up to my father in law.
Over the years we have cut pack quite a bit on what we prepare so that there are not a lot of leftovers.
We eat several leftover turkey sandwiches over the days after Thanksgiving (yum! so good!).
We boil the carcass and make turkey gumbo.
Then, if there's any left, I make cheesy turkey spaghetti, instead of cheesy chicken spaghetti.
