I personally prefer mandarin oranges, pineapple, bananas and coconut. Toss the bananas in pineapple juice with a few drops of lemon juice added. This will keep the banana white. For a nice presentation, then layer pineapple chunks, banana, and orange segments, and top with the coconut. Great for hot weather, when you want something sweet, but light.
For colder weather, blueberries, strawberries, and blackberries work great. Gently toss with some very chilled vanilla yogurt, then top with pecans.
