2 (8 oz.) containers strawberry yogurt
1 (8 oz.) Cool Whip
1/2 c. mashed strawberries
1 prepared 8 or 9 inch graham cracker crust

Combine the mashed fruit and yogurt in a bowl. Fold in the Cool Whip, blending well.

Spoon into crust and freeze for 4 hours, or thoroughly chill. Remove from freezer and place in the refrigerator 30 minutes before serving. Solid frozen pie may require more time for a softer texture.
