Preheat oven to 350 degrees F. and have a small baking dish or pie plate or small cast iron skillet out to use.

Place cream cheese, oregano, salt, garlic salt, pepper, mozzarella cheese and cheddar cheese into a medium sized mixing bowl, stirring to combine. Place cream cheese mixture into the bottom of your baking dish, spreading evenly. Top evenly with grated Parmesan Cheese then marina or pizza sauce. Top with more mozzarella cheese and layer with pepperonis. Bake for 30-35 minutes, until hot and bubbly. Edges will start to turn golden. Remove and garnish with sliced green onion or chopped parsley. Serve warm with your favorite crackers, little toasts, vegetables or chips for dipping.
