Barbara Kingsolver's Pizza Crust Recipe

3 tsp. yeast
1 1/2 c. warm water
3 tbsp. olive oil
1 tsp. salt
2 1/2 c. white flour
2 c. whole wheat flour

Dissolve the yeast into the warm water and add oil and salt to that mixture. Mix the flours and knead them into the liquid mixture. Let dough rise for 30 to 40 min. Once the dough has risen, divide it in half  and roll out two 12-in. pizza crusts on a clean, floured surface. Bake with toppings at 425 for aabout 20 min. until crust is browned on the edges and crisp in the center.
