I made this great turkey, fontina and cranberry sauce panini/grilled cheese using Thanksgiving leftovers, inspired by (but not exactly following) this recipe. I also saw some other turkey panini recipes on the internets that were really appealing!
In retrospect, I am thinking I would have liked to throw thinly sliced apple into the sandwich itself for some crunch, but it was pretty tasty nonetheless. Prior to composing the sandwich, I zapped the shredded turkey in the microwave with a splash of chicken stock to reconstitute it, as it got a little dry in the fridge overnight. Worked perfectly. I would definitely recommend this sandwich for leftover turkey! Also, this avgolemono soup recipe that I made in the past works great with some shredded turkey thrown in at the end!
