In a mixing bowl, beat the cream cheese and Italian seasoning. Spread in an ungreased 9-inch microwave-safe plate. In a bowl, combine the mozzarella and Parmesan cheeses; sprinkle half over the cream cheese. Top with the pizza sauce, remaining cheese mixture, green pepper and onion. Microwave, uncovered, on high for 3 minutes, or until cheese is melted. Serve with breadsticks or tortilla chips. Double the recipe, if you like, and keep it warm in a slow cooker for parties.
