This is so simple; it's my favorite fruit salad combination. My grandmother whips this up every holiday and serves it with fresh whipped cream; I like it topped with a sprinkling of granola. So healthy! This is best served about 2 hours after refrigerating. It's good, though, for 2-3 days in the refrigerator, but the banana will turn a little soft. (Cooking time is refrigeration, but you can eat it as soon as you prepare it too)
