When I fixed this recently, I was out of bananas and so I substituted fresh blueberries. I really like it both ways.
1 container frozen sweetened sliced strawberries, semi-thawed
1 can peach pie filling
Halved red and green seedless grapes
Fresh blueberries (optional)
Cool Whip for topping
Stir together. Serve chilled. Top with Cool Whip.
