Key lime juice
1 can sweetened condensed milk (nonfat is fine)
8 oz. whipped topping
1 graham cracker crust
Squeeze the lime into a measuring cup, then add key lime juice(or you can just use all fresh) to make 1/2 cup. Mix in the milk until very smooth. Add whipped topping. Combine well and pour into a graham cracker crust. Chill several hours. Couldn't be easier!
