Eggplants Baked with Tomato and Parmesan

Eggplant and tomato are excellent bedfellows; the sweet sharpness of the tomato adding much in the way of succulence to the bland flesh of the eggplant. Garlic and olive oil are almost certain to come along for the ride. What follows is a recipe I use over and again as a relatively quick supper, occasionally introducing mozzarella instead of Parmesan, and sometimes adding basil with the tomatoes.
