Hit the farmer's market yesterday and grilled some sliced eggplant and zucchini last nite. I brushed both the eggplant and zucchini after slicing with olive oil, balsamic vinegar and herbs. The zucchini was delicious. The eggplant was awful. It had an unpleasant, gummy texture and was tasteless. Anyone know what happened? I'd like to try again.
