Know how eggplant tends to get yukky and black if you don't hurry and do something with it after cutting? Here's my tip for today (love this theme, by the way):

Cut your eggplant as desired (sliced, diced). Add a tablespoon of milk to a medium bowl of tepid water and add in the eggplant. This will buy you time to prepare other ingredients or heat pans, etc. Drain just before use. The eggplant will not discolor.
