Grease a baking dish well. Cut the bread into about 20 slices. Place 8 slices on the greased bottom of the baking dish. Heat the fat in a pan. Peel onions and garlic and cut them into fine cubes or press the garlic cloves through a garlic press. Add to the hot fat and fry briefly until translucent.
Add the minced meat and fry for about 5 minutes, chopping through with a spatula. Mix with salt, pepper, chilli powder, tomato ketchup and Tabasco and season to taste. Then spread the minced meat on the layered bread. Clean and wash the zucchini and eggplant and pat dry with kitchen paper. Slice the zucchini and cut the eggplant into strips. Leave the aubergine strips to stand for 10 minutes. Then rub off the salt that has become moist in the meantime. Layer the vegetables on the minced meat. Spread 12 slices of bread fan-shaped on top. For the sauce, whisk the milk and egg yolk with the whisk of the hand mixer. Season with salt and pepper.
