I like fresh fruit salad, I would try to have some kind of stone fruit (plums, peaches), some kind of berries,grapes, pineapple, and some citrus fruit. Not crazy about apples in it. The citrus fruit adds ascorbic acid to make it last longer. NO COOL WHIP OF ANY KIND!!!!!!!YUCK!!!!! That stuff has high fructose corn syrup and partially hydrogenated vegetable oil in it - NOT good for you!!
You can make a good size batch of this and it will keep for several days in the fridge. If you want bananas in it I would add them one at a time as you are ready to eat it. Otherwise they get mushy.
The best part of fruit salad is the juice left at the bottom of the container.
