In a bowl add lukewarm water, sprinkle yeast over water in. Let stand for 5 minutes, then stir and dissolve yeast. In a large bowl add sugar, salt, margarine, 1/2 cup parmesan cheese, oregano and 3 cups of the flour. Beat at slow speed for 2 minutes. Beat in rest of flour; cover the bowl with a damp cloth or plastic wrap. Let rise in a warm place 45 minutes, or until doubled in volume. Preheat oven to 350°F (175°C). Lightly grease one round, 2-quart casserole. Set aside. Punch dough down for 1/2 a minute. Turn dough into casserole. Sprinkle with the remaining 1 tablespoon Parmesan cheese. Bake at 350°F (175°C) for 55 minutes. Cool on a wire rack.
