Put the ingredients all together in a pie shell, mix with a fork and pat down. Double the recipe if you want to have a top to your pie.Depending on the flour consistency (I get a really fine barley flour), you may need to play with the liquids. When you mix it, it should crumb.
Add your favourite fruit, veggies, tofu quiche or whatever!!! This recipe is so easy, I baked a pie while chairing a meeting once!
Bake as you would based on the ingredients you are adding.
