Does anyone have any idea....?

What can I do with a 10lb bag of potatoes which was left out in the truck all night and froze?

Now they’ve thawed and they’re mushy and soft.
I’ve picked through and was able to salvage about half of them, but I don’t like the idea of just throwing out 5 lbs of potatoes!
Anyone have a recipe which calls for frozen or ‘soft’ potatoes?
