For eggplants, you could cut each into strips, combine in a light batter, season to choice and make pancakes.

You could lightly steam the sliced eggplant and once they're done (cooked), you could serve with a dipping sauce; guacamole.

You could also dice up the eggplants, combine (cook) with pasta sauce and serve with pasta.

Another method would be to slice the eggplant into fan shapes, slit each down the middle and fill with a filling (whatever you wish) and then cook that in the oven.
