Preheat oven to 400°F. Grease pan. Whisk together dry ingredients. Separately, mix oil and water, then quickly mix into dry ingredients just until a ball forms. Adjust water as needed so that ball is not too crumbly. Roll dough and place in greased pan (patch as needed). Use form to prick holes. Pre-bake 3min for a pie with filling. Bake another 15min until brown.
