In a large mixing bowl, whisk together the garlic, tomato paste, pizza sauce, beef broth, water, Italian seasonings, oregano, salt, and onion and garlic powders. Pour this into the pan from which you drained the bacon grease. Stir well, raise the heat to high and bring the mixture to a boil. When it is boiling, gently stir in the dry pasta, add a lid to the pan and drop the heat to low. Cook for 10 to 12 minutes, stirring every couple of minutes to prevent the pasta from sticking. When the pasta is tender, turn off the heat, add all of the grated cheese, the crispy bacon, and the chopped pepperoni and stir gently until the cheese is melted in completely and everything is evenly distributed. Serve hot with additional grated cheese if desired.
