Strawberry Yogurt Pie

I went to lunch at my girlfriend's house today and I made this yogurt pie for the occassion. It turned out so delicious. I used lite/lowfat everything, so it made it VERY easy to justify eating it :)

12 oz. Cool Whip Dessert Topping
16-24 oz. Strawberry Yogurt (or any flavor you desire). I just kept adding more until it tasted good.
2 any brand ready-made graham cracker pie crust (or make your own)
1 cup sliced frozen or fresh strawberries (or whatever fruit you want)

Combine Cool Whip, Yogurt, and sliced fruit
Pour into pie crust
Cover with pie lid
Freeze for 3 hours or overnight
Remove from freezer about 20 minutes prior to serving
Top with additional Cool Whip and Strawberries if desired
I like to crumbled graham cracker on top for a little extra decoration
