Since it's summer and it is HOT, here is my mother’s refrigerator limeade pie, which you can make in five minutes and enjoy after it has a short chill in the fridge!
Refrigerator Limeade Pie
8 ounces frozen limeade, thawed
8 ounces whipped topping or whipped cream
14 ounce can condensed milk
Pre-made graham cracker or shortbread crust
Optional: green food coloring
Alternatively, you can use lemonade concentrate in the same amount, and leave uncolored or use a few drops of yellow food color, just for fun.
