I make soups often and freeze them. I usually microwave straight from the freezer, but I'll occasionally take a couple or more out and place in the refrigerator to thaw for DH and me to eat within a few days.
BTW one of our stores, Tops, also carries those Panera soups along with their mac and cheese. We get the mac and cheese often.
The pain they have cost us, the evils that never happened.
