fruit and yogurt salad

My mom frequently makes this salad and she made it for Kaylee's graduation party.  It is a simple fruit salad, just fresh fruit lightly coated in strawberry flavored yogurt.  We usually use a combination of red and green grapes and strawberries as they are usually readily available but many other fruits could be added such as berries like raspberries or blueberries, stone fruits like cherries, peaches or nectarines, and maybe kiwi or mango.  This salad would be great with fresh fruit in season, picked at its peak of ripeness.   For the graduation party it was dished into individual servings in clear wide mouth drink cups.  It was an easy way for guests to grab a cup on their way thru the line and refilling the tray with new cups was easy for the kitchen crew.  Serving only a few cups at a time eliminated the need to keep a salad bowl chilled throughout the open house as the salad could be taken from the fridge to fill a small tray of cups at a time.  Mom prepped the fruit ahead of time and the yogurt was added to small batches as needed.  Mom usually uses the Yoplait strawberry yogurt which is really good but I would think that any sweetened, flavored yogurt could be substituted.
