In a medium bowl, mix together the flour and the salt.
Add in the water and oil, and mix until fully combined. Form into a ball.
Grease your pie pan, and place the ball of dough on top. Punch down the ball, and spread the dough to cover the pie pan (I used a quiche pan), pressing the dough up around the sides of the pan.
Use to bake anywhere you need an unbaked crust!
