Here is my favourite eggplant recipe (other than Aloo Gobi-type dishes):
Cut the eggplant into 1/4" rounds and salt them. Let them sweat for 10 min. then wash the salt off and pat dry. (this removes some of the moisture)
Put them on an oiled baking sheet and drizzle with olive oil. Put them under the broiler for about 10 min.
Take out the tray, flip the eggplants and crumble goat cheese bits over them like little pizzas. Put them back under the broiler and cook until the cheese is toasted with a little bit of brown and the eggplants are cooked. (~6 min.)
Take out the eggplants, drizzle with balsamic vinegar and sprinkle with fresh minced herbs (scallions, basil and parsley work great, as do others....)
