Dissolve yeast and sugar in warm water in a large bowl; let it stand until it starts to bubble. In the meantime, assemble the other ingredients. Mix salt, oil, spices and 1 cup flour into the dissolved yeast. Beat well. Add remaining flour, 1/2 cup at a time, beating well with spoon. When you have a very stiff dough, use your hands to mix in just enough of the remaining flour so that your dough is no longer sticky. Knead 20 turns and place dough into a warm, oiled bowl. Cover with a damp towel or plastic wrap. Let it rise in warm place for 30 minutes. Punch down the dough and pat onto a greased pizza pan. Let rise again for 20 minutes. Top with your favorite, garlicky tomato sauce and choice of toppings. (Note: I?ve found that wilted spinach and feta cheese makes a good pizza. Adding as much as you prefer.) Place in cold oven, on the lowest rack and turn the heat to 500°. Bake for 20 minutes or until nicely browned.
