We love this easy (SO EASY) and delicious dessert that is NO BAKE!
Add in the whipped topping (cool whip) and the crushed pineapple. Using a spatula, gently mix until fully incorporated.
In a 10x 15 casserole dish (or 9x13 dish, but nothing smaller) that has been sprayed with non-stick spray, add 3 cups of the graham cracker crumbs. (You should have 1 cup remaining.) Press until flat and even.
