Combine yeast, 2 cups flour and salt. Heat water until very warm (120° to 130°). Gradually beat water into dry ingredients until just blended. Beat 2 minutes at medium speed. Add 1/2 cup flour to make a thick dough; continue beating 2 minutes. Stir in enough additional flour (about 1 1/2 cups) to make a soft dough. Turn dough onto floured surface; knead until smooth and elastic, about 8 minutes, adding more flour while kneading, if necessary. Shape dough into bait; place in greased large bowl, turning over so top is greased. Cover; let rise in warm place until doubled, about 1 hour. Punch down dough and cut in half. Roil dough out into 2 (11- to 15-inch approximately) oblongs. Spread tomato sauce over dough. Sprinkle on pizza seasoning. Add sausage and other toppings. Cover with cheese. Bake at 400° to 425° for 15 to 20 minutes. Makes 2 pizzas.
