To prepare dough, dissolve yeast in warm water in a large bowl, and let stand 5 minutes. Lightly spoon flour into dry measuring cups; level with a knife. Add 1 3/4 cups flour and salt, and beat with a mixer at medium speed until smooth. Turn dough out onto a floured surface. Knead until smooth and elastic (about 10 minutes); 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, 45 minutes or until doubled in size. (Press two fingers into the dough. If an indentation remains, dough has risen enough.) Punch dough down; knead 5 times, and let rest for 15 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.
To prepare the topping, heat the oil in a large nonstick skillet coated with cooking spray over medium-high heat. Add the fennel and the next 5 ingredients (fennel through black pepper), and cook for 20 minutes or until golden, stirring frequently.
Preheat oven to 450°.
Spread sauce over crust, leaving a 1/2-inch border; sprinkle with fennel mixture, cheese, and olives. Bake at 450° for 18 minutes or until browned.
