Dad's Favorite Pizza Recipe

In a large bowl, dissolve yeast in warm water. Add the butter, eggs, grated Parmesan, salt and 2 cups flour. Beat until smooth. Stir in enough remaining flour to form a soft dough. Turn onto a floured surface; knead until smooth and elastic, about 5 minutes. Place in a greased bowl; turn once to grease top. Cover and let rise in a warm place until doubled, about 1 hour. Punch dough down; let rest for 5 minutes. Grease a 14-in. deep-dish pizza pan; sprinkle bottom with cornmeal. Press dough into pan; build up edges slightly. In a large skillet, cook the beef, sausage and onion over medium heat until meat is no longer pink; drain. Spread pizza sauce over dough to within 1 in. of edges; sprinkle with meat mixture. Top with the mushrooms, pepperoni, ham, olives, mozzarella and shredded Parmesan. Bake at 400° for 30-35 minutes or until crust is golden brown and cheese is melted. Yield: 8 slices.
