I am craving eggplant on my pizza that I am going to make tonight, and I am wondering what is the best way to prepare it???

do I wash it and then oil it a little then salt it a little and grill/roast it for a while then put it on my pizza or do I just pop it on there???

I have never in my life brought an eggplant let alone prepared one but in the area we use to live the pizza shop put it on my pizza and I just loved it so I am really REALLY wanting it atm.

Thanks for any help its appreciated
