Preheat the broiler to 425 degrees F. Sprinkle the olive oil over the cut crusty bread. Sprinkle with the garlic powder. Spread the marinara up and over and cover with the dried basil and oregano.
Combine the cheeses as one. Equitably sprinkle them over the sauce. Top with the pepperoni. Heat for 15 to 20 minutes, until the cheddar is brilliant and effervescent.
Eliminate from the stove and top with additional parmesan and the new spices. Cut and serve.
