2 (8 oz.) containers fruit flavored yogurt
Mashed fruit (what ever flavor yogurt)
1 (8 oz.) Cool Whip
1 (9 inch) graham cracker crust

Fold yogurt and fruit into Cool Whip. Blend. Spoon into crust and freeze 4 hours. Place into refrigerator 30 minutes or longer before cutting. When using berries such as huckleberries or blueberries I do not mash but a handful.
