Lemonade Pie

Here is a perfect dessert for a summer day.  Light, fluffy and easy:

•1 graham cracker pie crust

•1 14-ounce can sweetened condensed milk
•1 6-ounce can of frozen lemonade concentrate, thawed (could use a full, 12 oz. can if desired, but it will be strong).
•1 medium size (8 ounce) container of Cool Whip, thawed
Preparation:
Beat together condensed milk and lemonade; fold in Cool Whip. Pour into pie crust. Freeze for at least 3-4 hours until firm.
