1. In a large bowl, dissolve yeast in warm water. Add 1 cup flour, oil and crust seasonings; beat until smooth. Add enough remaining flour to form a soft dough.
2. Turn onto a floured surface; knead until smooth and elastic, 6-8 minutes. Place in a greased bowl; turn once to grease top. Cover and let rise in a warm place until doubled, about 1 hour.
3. Punch dough down; roll out into a 15-in. circle. Transfer to a well-greased 12-in. heavy ovenproof skillet or round baking pan, letting crust drape over edges. Sprinkle with 1 cup mozzarella.
4. In a skillet, sauté the green peppers, onion and topping seasonings in oil until tender; drain. Layer half the mixture over crust. Layer with half the Parmesan, sausage and tomatoes. Sprinkle with 2 cups mozzarella. Repeat layers. Fold crust over to form an edge.
5. Bake at 400° for 20 minutes. Sprinkle with pepperoni and remaining mozzarella. Bake until crust is browned, 10-15 minutes longer. Let stand for 10 minutes before slicing.
