Frozen Lemon Pie

1 1/2 cups graham cracker crumbs
1/4 cup butter, melted
1/2 gallon vanilla ice cream, softened
1 (8 oz) tub whipped topping, thawed to room temperature
6 oz (undiluted) lemonade frozen concentrate
Juice and zest from 1 lemon
1 lemon, sliced
Mint leaves

Prepare a graham cracker crust by combining graham cracker crumbs and melted butter.  Pat into a 9 or 10 inch greased pie plate to form a crust.  Chill or freeze until firm.  In a large bowl combine softened ice cream, whipped topping, lemonade concentrate, and the juice and zest of 1 lemon.  Stir until blended.  Pour over chilled pie crust.  Freeze overnight or for several hours.  Garnish with lemon slices and mint leaves.
