Whole Wheat Margherita Pizza

1. In a medium mixing bowl, combine yeast and warm water; let sit until yeast foams, about 5 minutes. Stir in oil and salt. Add flour, 1/2 cup at a time, mixing with a large spoon, until dough comes away from the side of the bowl and holds together. 2. Sprinkle additional flour on to work surface. Turn out the dough and knead about 5 minutes, until it is smooth and springy, adding only enough flour to keep it from sticking to the board. 3. Form dough into a ball; place in a medium bowl. Cover with plastic wrap and put in a warm place. Let rise until doubled in size, about 2 hours. 4. To make pizza, pre-heat oven to 475 °F (250 °C). Place dough on lightly floured work surface; flatten with your hand. Using floured rolling pin, roll dough outward from the center. Form dough into a circle or rectangle about 1/4" thick. 5. Sprinkle pizza stone or baking sheet with cornmeal. Lay crust on stone or sheet. Lay alternating slices of tomato and cheese on top of the crust, slightly overlapping each piece. Lightly drizzle with additional oil, if desired. 6. Let pizza rest 10 minutes. (This step can be skipped, but it makes for the crispiest crust.) Place pizza in oven and bake 20 minutes, or until cheese is melting and browning a bit. Sprinkle pizza with sliced basil leaves. 7. Note: If you don't have a rolling pin, use a wine bottle or stretch the dough out with your hands. If the dough springs back too much, let it rest for 3 minutes to relax the gluten. The cornmeal on the pizza stone or baking sheet makes the crust dry and crunchy. The basil shouldn't go on until after baking, or it will burn.
