How to Make It
In a large bowl, whisk 1/2 cup of the olive oil with the vinegar, parsley, basil, cilantro and two-thirds of the garlic. Add the eggplant slices and coat well. Marinate for 15 minutes.
Light a grill. Grill the eggplant over moderate heat, turning and basting occasionally with the marinade, until nicely charred and tender, about 10 minutes. Chop the eggplant.
In a large bowl, combine the remaining garlic with the mayonnaise and lemon juice. Gradually whisk in the remaining 1/4 cup of olive oil. Fold in the chopped eggplant and season with salt and pepper. Serve with crackers.
