This is easy – and economical!
For a single pie crust:
1 1/2 cups flour
1/2 tsp. salt
1/3 cup vegetable oil
3 to 3 1/2 Tbsp. cold water
(Reserve about 1 Tbsp. to see if all the liquid is needed.)
Mix all ingredients with a fork. Roll between two sheets of wax paper. (Frugal tip: Use an opened-out cereal bag OR two opened-out bread bags!) Peel off one sheet of wax paper, invert the dough into a pie pan, and fit it gently in. Gently remove the other sheet of wax paper.
Bake at 450 degrees F for 8 to 10 minutes.
