Lay the eggplant cut-side up on a baking sheet. Drizzle the eggplant with olive oil or another type of vegetable oil. Use a pastry brush or the back of a spoon to smooth the oil over the eggplant until the flesh is lightly coated all over. Sprinkle the slices with salt and pepper. Place the eggplant in the oven and bake it until the inside is creamy and the edges and surface have turned brown and crispy, about 20 minutes.  If you'd like cheesy eggplant, remove it from the oven and sprinkle it with Parmesan, cheddar, or goat cheese. Place it back in the oven for another 5 minutes, until the cheese is melted. For another variation, try tomato garlic eggplant. Place tomato halves and garlic cloves around the eggplant slices and bake them together for 30 minutes.
