Ahhh. Good idea. We had a "hot bag" so to speak. A reusable bag with some sort of foil inside that is supposed to keep things hot inside. I think someone brought it home when they bought a rotisserie chicken from the supermarket. I cut it up and put it on the outside...but I think now I am going to put it on the inside. Seems to make sense that would work better.
