Clean and wash the aubergine and cut it diagonally into slices of approx. 1 1⁄2 cm thick. Sprinkle 4 slices with a little salt, dice the remaining slices. Peel onion and cut into strips. Peel garlic and cut into thin slices. Clean, wash and cut the bell peppers into strips.
Boil up approx. 2 l salted water (1 teaspoon salt per litre). Heat 2 tablespoons of oil in a frying pan. Stir-fry the bell peppers, diced aubergines, onion and garlic for about 5 minutes. Add tomatoes, bring to the boil and braise for about 5 minutes. Season to taste with salt, pepper and maple syrup.
Cook the pasta in boiling salted water according to the instructions on the packet. Whisk the egg in a deep dish. Dab aubergine slices dry. Turn first in flour, then in egg and finally in breadcrumbs. Heat 4 tablespoons of oil in a frying pan. Fry the aubergine slices in this oil over medium heat for about 3 minutes on each side.
Drain the pasta, put it back into the pot and mix with the tomato sauce. Serve with aubergine cutlets. Slice parmesan cheese over it.
