Preheat your oven to 350 degrees.
In a large bowl, mix together the cream cheese, 1/2 cup of mozzarella cheese, parmesan cheese, oregano, basil, garlic salt, pizza sauce, and mini pepperoni.
Using a serrated knife, cut out the middle of the round loaf of bread, like you would do to make a bread bowl for soup. Cut the part of the bread that you removed up into cubes and reserve for serving.
Put the cream cheese mixture into the loaf of bread. Top with the remaining mozzarella cheese and then some mini pepperoni. Cover with aluminum foil and place directly on the oven rack. Bake for 20 minutes. Uncover and bake for a remaining 10 minutes.
Serve immediately with the reserved bread and bruschetta chips.
