Peel garlic and chop very finely. Mix Teriyaki sauce, lime juice and garlic. Clean and wash spring onions and cut into rings.
Dab aubergines dry. Grill them on the hot grill on each side for about 3 minutes. Then brush with marinade and grill for a further 5 minutes while turning, brushing several times with remaining marinade. Sprinkle with spring onions and sesame seeds.
