Nana insists this 4 ingredient wonder is the reason grandpa married her. I whipped it up in 5 minutes yesterday and completely understand why.

4. Refrigerate the pie for at least 4 hours, or until firm enough to slice cleanly. For a firmer texture, chill it overnight.

5. Slice and serve cold. If desired, top each piece with a little extra whipped topping or a thin lemon slice for a simple finishing touch.
