This has become my go-to pot luck recipe. Fresh, fast, easy, and light -- it's a real crowd pleaser! I always double this recipe. When I'm short on one fruit, I just substitute another, and no one is the wiser. I use a fat-free raspberry vinaigrette, and I always use 1/2 the amount called for. You can always add more dressing, if you feel you need it, but it is impossible to take it away if it seems too much, so start with 1/4 cup and work your way up. Due to the dressing I use, I skip the sugar all together.
