Once you finish slicing the Oreo's in half, take the pie out of the freezer and easily press the Oreo's into the filling.
Once finished pressing in the cookies, take the remaining Cool Whip (Slightly soft to spead easily) and easily cover the pie. Sprinkle on the ground Oreo's. You will have a lot of cookie for the topping. You may choose to use more or less cookie crumble.
