In large bowl, dissolve yeast and sugar in water; let stand for 5 min. Add oil and salt. Stir in flour, a cup at a
time, to form soft dough. Turn onto floured board; knead until smooth and elastic, about 2-3 min. Place in greased bowl, tuning once to grease top. Cover and let rise in a warm place until doubled, about 45 min. Meanwhile, brown beef and onion; drain. Punch dough down;
divide in half. Press each into a greased 12" pizza pan. Combine the tomato sauce, oregano and basil; spread over each crust. Top with beef mixture, green pepper and cheese. Bake at 400 degrees for 25-30 minutes or until crust is lightly browned. Yield 2 pizzas
