Hi Kathy,
Here you go..., found it on the web somewhere...is good and easy(best part)


Lemon Pie
1 9 inch graham cracker crust
1 14 oz. can sweetened condensed milk
1/2 cup lemon juice
1 8 oz. carton Cool Whip, thawed

In a bowl, combine milk and lemon juice, mix until smooth. This will begin to
thicken. Fold in cool whip and spoon into crust. Chill til ready to serve.
Enjoy!
