I added my comment on the bottom. It really was a surprise to me to learn that 'traditional meals-on-wheels are frozen and then reheated to be delivered hot'.
I would guess that it might be a surprise to others, too! I imagine that many people think they are getting a freshly-cooked hot meal and in fact they're getting a reheated one.
