Prepare medium charcoal grill. Place aubergine slices on large tray or baking sheet and sprinkle with coarse salt. Let stand to release moisture, about 20 minutes. Drain, rinse and pat dry. Sprinkle aubergine slices on both sides with pepper, basil, parsley and garlic. Grill over medium coals until wilted but not overcooked, sprinkling with vinegar while cooking.
