Frozen Lemonade Pie

14 ounces sweetened condensed milk
6 ounces frozen lemonade concentrate, thawed and undiluted
12 ounces frozen fat free whipped topping, thawed
2 (9 inch) reduced fat graham cracker pie crust
In a large bowl, mix together the sweetened condensed milk and lemonade concentrate.
Fold the whipped topping in slowly, keeping as much air in the mixture as possible.
Spoon into crusts.
Freeze until firm–I suggest about two hours minimum.
Remove from the freezer half an hour before serving, to allow the pie to thaw to a creamy state.
