Somehow, this thread caused me to go out and buy a Hormel canned ham. Expiration date is late in 2021 so no problem there, but a curiosity:
The can clearly states that it's precooked and can be opened, sliced, and eaten cold. BUT ... if you want it warm/hot, they want you to bake it for an hour at 325 degrees, and check it with a meat thermometer for 165 degrees. If it's already fully cooked ... what difference does it make?
