That's what happened, I imagine.
Perhaps it was too loosely wrapped in my bag and when warm air hit it, condensation occurred. That's a possibility too.
It was not frozen for very long. A couple of days max.
That's why I think you need to pack a sandwich air tight as possible.
One is not going to cook off extra moisture before eating it.
A vacuum sealer would be good for packing and freezing sandwiches I think.
You would think the prepared food industry would have solved this and frozen ready to eat sandwiches would be a standard part of every kids lunch box.
It solves two problems at once; 1- you get lunch and 2- you get a free ice pack with every purchase
