Pour half of the sauce into the skillet and layer half of the sautéed eggplant slices over the sauce. Top with half the shredded mozzarella and parmesan cheeses. Sprinkle the fresh basil on top. Repeat these steps to create a second layer. Drizzle a little extra-virgin olive oil over the top, and transfer the skillet to the oven. Bake for 15 minutes or until the cheese is melted and bubbling. Let cool in the pan for 5 minutes. Garnish with remaining fresh chopped basil and more parmesan cheese, if desired.
