I actually made this pie at least 2 weeks ago. I got the recipe from an old Taste of Home magazine. It was really, really easy and delicious. Definitely a good one for a hot summer day. I added just a little more lemonade then what was called for and omitted the yellow food coloring. (yes, the picture is from Taste of Home; I will upload my later).
1 can (14 oz) sweetened condensed milk
1 can (6 oz) frozen lemonade concentrate, partially thawed
2-3 drops yellow food coloring, optional
1 carton (8 oz) frozen whipped topping, thawed
1 graham cracker crust (9 inches)
Lemon slices and fresh mint, optional
In a large bowl, combine milk, lemonade and food coloring. Fold in the whipped topping; spoon into crust. Chill until ready to serve. Garnish with lemon slices and mint if desired.
