Frozen Key Lime Pie

Easy, cool, refreshing goodness!

1 (12 oz) container cool-whip (thawed slightly)
1 (14 oz) can sweetened condensed milk
1/2 cup lime juice
1 prepared pie crust (graham cracker, vanilla wafer, or shortbread all work well)
grated lime zest for garnish (optional)

Mix sweetened condensed milk and lime juice together. Mix in cool whip until well blended. Spoon into pie crust. Freeze until firm 1-3 hours. Remove crust from tin and cut into 6-8 wedges. Garnish with lime zest and/or cool-whip. Enjoy!
