Preheat oven to 350 degrees. In a medium bowl, mix together cream cheese, oregano, basil, cheddar cheese and ¾ cup of the mozzarella cheese.
Spread cheese mixture into a small casserole dish. Top with half of the remaining cheese and Ragu sauce. Sprinkle with remaining cheese and pepperonis.
Bake 25 minutes or until the dip is bubbly. Serve with tortilla chips!
