Wash and clean the zucchini, cut in half crosswise. Cut lengthwise into thin slices. Peel and finely chop the onion. Wash the thyme, dab dry and remove the leaves. Separate eggs.
Mix egg yolk, milk, mineral water and flour to a smooth dough. Stir in parmesan cheese and thyme. Season with salt, pepper and nutmeg. Heat the oil in an ovenproof pan. Fry zucchini and onions for 2-3 minutes. Beat the egg whites until stiff, fold into the prepared dough. Spread the salami in the pan, fry briefly and pour the dough on top. Put the pan into the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3). Let the dough set for about 10 minutes. 5 minutes before the end of the baking time, spread cheese on the pancake.
