4 cups all-purpose flour

1 1/2 cup warm water (about 110 degrees)

2/3 cup whole-wheat flour

1 tablespoon olive oil

1 package active dry yeast

1 1/2 teaspoons salt

1 teaspoon sugar

Combine water, oil, yeast and sugar in a small bowl. Let stand 5 minutes or until it bubbles.

Mix flours and salt together thoroughly in a food processor or mixer. Add water mixture while blending. Let mix for 2 minutes.

Knead briefly on a lightly floured surface. Place in a large oiled bowl and let stand in a warm place for 2-3 hours. It should double in size. Once the dough has raised, lightly flour two cooking sheets.

On a floured surface roll out 1/4 of the dough into a circle about 1/8 inch thick. Place on cooking sheet. Repeat process until you have four rounds.

Place one pizza on a clean, oiled and preheated grill. Grill pizza crusts for about 1 minute or until the bottom is brown. With tongs, gently flip it over and grill for an additional 30 seconds. Remove from grill and repeat with remaining pizzas. Let cool.

Top with your favorite pizza toppings and return to a preheated grill for about 2-3 minutes. Watch carefully to avoid burning. It's best to grill one pizza at a time.
