I think repurposing leftovers requires some of the most practical creativity. Particularly turkey - that's a massive amount of animal (at least for the urban household) to jig, cut&paste, and spin magic on.
My mom's favorite go-to was saving all the remaining pieces of turkey meat pulled from the bones and using them for turkey tacos - deep-fried turkey tacos. She'd also use the remaining shreds in turkey curry (Japanese-style pseudo curry). She'd save the bones and use those for a base for stock, and then use that stock for the curry.
