Wash parsley, shake dry, pluck off leaves and chop. Season crème fraîche with salt and pepper. Stir in parsley, except for 1 tbsp.
For the sauce, peel and finely dice the onion and garlic. Wash and chop the tomatoes. Heat 2 tablespoons of oil in a saucepan. Fry the onion and garlic in it. Add the tomatoes. Season with salt, pepper, 1 pinch of sugar and harissa.
Simmer the sauce open at low heat for about 30 minutes.
In the meantime clean, wash and slice the aubergines. Heat about 10 tbsp. of oil one after the other in a large frying pan. Fry the aubergines in it in portions, turning them golden brown. Take them out and let them drip off on kitchen paper.
Season the tomato sauce to taste again. Spread about half the crème fraîche on a plate. Spread a part of the eggplant slices and the sauce on top. Layer the crème fraiche, aubergines and sauce alternately.
Finish with Sugo. Sprinkle the rest of the parsley over it. Add ciabatta.
