In a medium bowl, combine flour and salt. Stir in oil and water and mix until just combined. Form dough into ball and place it in a greased pie pan. Press dough out evenly until it covers entire pie pan including the sides. Make sure you press it thin where the side and bottom meet. Crimp edges if desired.
To pre-bake, poke with fork and bake at 400 degrees F for 10-15 minutes.
