Rinse the eggplant and cut into slices. Lightly salt the eggplant slices and set aside for 15-20 minutes.
Peel and finely chop the onion and garlic. Heat 2 tablespoons of olive oil. Saute the onion, garlic and provencal herbs. Add the tomatoes, crush finely and boil down into a thick, creamy sauce. Stir occasionally. Season with salt and pepper.
Pat the eggplant slices dry. Saute in the remaining olive oil.
Spread the eggplant slices in a baking dish. Pour the sauce on top. Sprinkle with parmesan. Preheat the oven to grill and bake until golden brown. Serve garnished with fresh herbs.
