To prepare the sauce, place a small saucepan coated with cooking spray over medium heat until hot. Add garlic, and sauté 1 minute. Add the dried oregano, 1/4 teaspoon salt, red pepper, and tomato sauce; reduce heat, and simmer 20 minutes, stirring occasionally. Stir in parsley, and keep warm.
To prepare crust, lightly spoon flour into dry measuring cups, and level with a knife. Dissolve sugar and yeast in warm water in a large bowl, and let stand 5 minutes. Add 1 1/4 cups flour and 1/4 teaspoon salt; stir until a soft dough forms. Turn dough out onto a lightly floured surface. Knead until smooth and elastic (about 10 minutes), and add enough of remaining flour, 1 tablespoon at a time, to prevent dough from sticking to hands (dough will feel tacky).
Place dough in a large bowl coated with cooking spray, turning to coat top. Cover and let rise in a warm place (85°), free from drafts, 30 minutes or until doubled in size. (Press two fingers into the dough. If indention remains, the dough has risen enough.)
Preheat oven to 450°.
Punch dough down; cover and let rest 5 minutes. Roll dough into a 12-inch circle on a floured surface. Place dough on a 12-inch pizza pan or baking sheet coated with cooking spray and sprinkled with cornmeal. Crimp edges of dough with fingers to form a rim. Cover and let rise 10 minutes.
Spread sauce over pizza crust, leaving a 1/2-inch border; top with pepperoni. Sprinkle with cheeses. Bake at 450° for 10 minutes or until crust is puffy and lightly browned. Remove pizza to cutting board; cut into 6 slices.
