I found this recipe years ago when I was too lazy to roll out a bottom pie crust, but didn't want to use one from the store. It's super easy, and works great for pies that don't need a top crust.
In a medium bowl, combine first 3 ingredients.
Add oil and milk, blend well.
Pat into a 9 inch pie pan.
Fill and use like a regular pie crust, or bake alone at 425° for 10-12 minutes.
