Preheat oven to 360 degrees
Mix together cookie crumbs, sugar, and salt (if using) in mixing bowl.
Melt the butter in your microwave
Drizzle a third of the butter into the sugar/cookie mixture, blending it with a spatula.
Continue the above the second third, then with the final third of the butter. Don't add the butter all at once since it will clump up and won't properly mix.
Cover the bottom of your pie plate with parchment paper to help keep the crust from sticking. (optional)
Dump the butter and cookie crumb mixture into your pie plate, and use your fingers to press it down and start to shape it to the sides of the plate.
Use a flat-bottomed measuring cup or glass finish pressing and shaping the crust. Pay particular attention to the sides.
Bake for five to ten minutes to set the crust.
Cool to at least room temperature before using. If it will be more than an hour before you use it, cover it with plastic wrap and refrigerate.
