lay the slices on a cookie sheet and freeze them
put the frozen banana slices in a food processor, and process.

It will turn into soft-serve ice cream. I promise!
You can add a glop of peanut butter, a little bit of chocolate, some cinnamon, other types of fruit, or anything you like!
OMG! I’m never buying ice cream from the store again!!!!
