Rhonda that sounds like a very good salad but I for one can not deal with mayo in/on fruits. Maybe only one fruit, a banana and peanut butter sandwich, loved those as a kid. Nice it has the option of cool whip I would use whipped cream.
Most of the jello salads are made with or served with mayo.
Those that will take desserts will make the gooey super sweet type things, those are always at our church meals.
