4 Ingredient Frozen Pie:
2 6oz containers yogurt (not greek)
8oz whipped topping
prepared graham crust
Dissolve jello mix in 1/4C boiling water. Whisk in yogurt, then fold in cool whip. Pour into prepared crust and freeze for at least 2 hours, or overnight preferably. You can change out the yogurt and jello flavors. I make this with SF jello and sometimes lowfat yogurt and it works just fine.
