Thanksgiving is all about gratitude, but sometimes it feels like its all about the leftovers. (which are something to be grateful for all on their own. ) you can throw them together in a sandwich, or just reheat em on a plate, but this lasagna is a little more of a creative way to compile them. Its an easy layered affair that gets all the best flavors of thanksgiving together in every bite, and so its quickly become our top choice of how to enjoy the remainders of a feast.
