In a large mixing bowl, add the yogurt and the dry powdered pudding and mix well until the little "lumps" are practically gone.
Mix in thawed Cool Whip.
Gently fold in the fruit and gently mix until all combined.
Refrigerate until ready to serve.
Notes
This recipe is best if made the day you are going to serve it.
If you make this recipe with frozen berries, you can choose whether or not to thaw them before using them. Occasionally, I like to make this salad a few hours before serving. When I do this, I leave the berries frozen. They thaw in the refrigerator in the salad and make a delicious "berry sauce."
Other flavor combinations that work well with this salad include the following: orange yogurt, vanilla pudding, and mandarin oranges; strawberry yogurt, cheesecake pudding, and fresh strawberries; blueberry yogurt, lemon pudding, and blueberries (fresh or frozen); coconut yogurt, vanilla pudding, and pineapple tidbits; and raspberry yogurt, cheesecake pudding, and fresh raspberries.
