Pulse the Oreos in a food processor until the cookies have become a fine crumb. Pour in the melted butter and pinch of salt and blend until combined.
Pour your crumb mixture into a 9 inch or 10-inch pie pan and press evenly into the bottom of the pan and up the sides of the pan. You can use the bottom of a flat glass or a flat measuring cup to really press it in well and get a nice, even crust.
Bake for 10 minutes.
Allow cooling completely before adding your chosen pie filling.
