We learnt the conditions necessary to allow חזרה on Shabbos.
Is there a permissible way to take cooked food from refrigerator and reheat it on Shabbos?
We learnt yesterday the מגיד משנה על הרמב”ם ה’ שבת פרק כב הלכה דף who brought the רשב”א who ruled it is permitted to place a pan of a dry fully cooked solid food next to a fire to reheat on Shabbos. Similarly it is permitted to place a pan of a dry fully cooked solid food on top of a pot which is on the fire.

Why does the Shulchan Aruch only permit חזרה to an empty pot and not to place it on the empty pot like in סע’ ה?
