1 can Eagle Brand condensed milk
1 lg. container Cool Whip
1 sm. can limeade (thawed)
Green food coloring
Graham cracker crust

In a large mixing bowl, combine the limeade and milk. Add food coloring until it is as green as you like. Add all the Cool Whip and beat with an electric mixer until it is mixed well. Spoon into the prepared crust which has been baked (you can buy them prebaked in the pastry section of your supermarket) and refrigerate one hour. (This keeps well for days in the refrigerator.)
