1. Soak some wooden skewers in water for 15 minutes. Stab each onion slice with a skewer to hold it together. Marinate the onions and eggplant for 15-20 minutes and preheat an outdoor grill on medium while you wait.
2. Remove the vegetables from your marinade and save the excess. Move the vegetables to the grill; grill for 15-20 minutes until tender, basting with the marinade a few times and turning once. During the last few minutes, toast the buns on the grill.
3. Top the buns with the eggplant, onion, lettuce, tomato, and whatever condiment you like.
