Light No Bake Key Lime Yogurt Pie

"This easy no bake frozen yogurt pie is perfect for the summer season! It takes only a handful of ingredients to put this pie together: graham cracker crumbs and oil for the graham cracker crust, light frozen whipped topping (like Cool Whip), key lime juice, key lime zest, and regular or Greek yogurt. This simple no bake pie is also on the lighter side so you do not have to feel guilty about serving yourself up a slice or two! We make this recipe all of the time and love how fresh and tasty this pie is!"
