Slice half of one large ball of fresh mozzarella.
Place Ravioli in an oven safe baking dish in one layer. Dollop spoonfuls of Marinara sauce over Ravioli and rip mozzarella slices into pieces. Scatter on top of Marinara and Ravioli. Add basil sprigs and drizzle with extra virgin olive oil, salt, and pepper. Transfer to a 375 degree oven and cook until Marinara is bubbling, pasta is cooked, and cheese is melted. Serve.
