Wash, clean and cut the aubergine lengthwise into about 8 slices (about 0.5 cm thick). Place on a baking tray, sprinkle with salt and set aside. Peel 1 clove of garlic, chop finely and mix with the oil.
Wash, clean and cut the tomato into 8 slices. Drain mozzarella and cut into 8 slices. Rinse aubergine slices, dab dry and grill on the preheated grill for 2-3 minutes.
Wash herbs, shake dry. Peel and slice 1 clove of garlic. Briefly grill the herbs and garlic slices in a grill tray. Lightly brush the aubergine slices with garlic oil and season with salt and pepper.
Pluck sage leaves from the stems. Pluck rosemary twigs a little smaller. Place a slice of tomato, cheese and herbs on each slice of aubergine. Season again with salt and pepper, fold over the aubergine and garnish with sage flowers and garlic slices.
Best served immediately.
