Cut mozzarella into 16 strips. Dab schnitzel dry. Cut ham and schnitzel in half crosswise. Spread the schnitzel with pesto, cover with Parma ham and roll up with one piece of mozzarella each
Peel and halve the shallots. Wash the lemon and about 24 bay leaves and dab dry. Cut lemon into slices. Clean, wash and cut the aubergine into pieces. Put involtini, eggplant pieces, shallots, bay leaves and lemon slices alternately on 8 skewers
Spread a grill pan thinly with oil and grill 2 skewers each for about 4 minutes while turning. Season with salt and pepper and place on a fat pan. Place in the preheated oven (electric cooker: 100 °C/ convection oven: 75 °C/ gas: unsuitable). Grill the remaining skewers one after the other in the same way and let them simmer in the oven. Arrange the skewers on a large plate and garnish with fresh lemon wedges
