Preheat oven to 375 degrees. Slice Italian loaf in half lengthwise. On a cookie sheet, cut side up, spread evenly the pizza sauce on both halves. Use as much as you like. Some prefer more than others... Top with the shredded cheese. Use plenty! Using an 8 ounce package, you will have enough. Spread out to within half an inch of the edge of the bread.
Then top with the toppings of your choosing. In the photo, I used Canadian Bacon, Pepperoni, chopped onion and chopped golden sweet bell pepper. But you may add whatever you prefer. Get creative! :-)
Place in the oven (center rack) and bake for about 30 minutes. Then increase heat to 425 degrees and bake an additional 10 minutes, or until your pizza is as browned as you like it. Remove from the oven, slice and serve! Serve with crushed red pepper and grated parmesan cheese (optional).
