Preheat oven to 400 degrees. In a large bowl, combine the oil and yogurt, mixing well. In a separate bowl, combine the flours and salt. Stir into the oil-yogurt mixture, 1/4 cup at a time, until well combined. Roll the mixture into a ball and flatten it into a thick pancake. Wrap in waxed paper and refrigerate 20 minutes. Between two sheets of waxed paper, roll the chilled dough into a large circle. Transfer dough into a 9" pie plate and chill for 15 minutes. Add pie filling of your choice and bake according to directions.
