There are lots of recipes out there that don't include any white flour. I personally feel that adding a little white flour makes a considerable difference in taste and texture. Here is a recipe that I got from www.animalvegetablemiracle.com
3 tsp. yeast
1½ cups WARM water
3 tbs. olive oil
1 tsp. salt
2½ cups white flour
2 cups whole wheat flour
To make crust, 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 minutes.
Once the dough has risen, divide it in half and roll out two round 12 inch pizza crusts on a clean, floured countertop, using your fingers to roll the perimeter into on outer crust as thick as you like. Using spatulas, slide the crusts onto well floured pans or baking stones and spread toppings.
