Soak 1 slice of ciabatta in cold water. Dice liver and bacon very finely. Peel garlic and press it through a garlic press. Wash the sage and dab dry. Pluck off leaves and chop approx. 4 leaves finely. Squeeze the bread well, mix well with liver, bacon, sage and egg yolk. Season with salt and pepper
Dab meat dry. Thinly flatten escalopes with a heavy saucepan or meat tenderizer. Spread each cutlet with approx. 1/8 of the filling. Cut each slice of meat into quarters. Roll up, season with salt and pepper. Halve 8 slices of bread
Put the meat rolls, bread and sage on small skewers, except for something to garnish. Distribute on a baking tray. Drizzle oil over it, pour on approx. 100 ml water. Cook in the preheated oven (electric cooker: 200 °C/ circulating air: 175 °C/ gas: level 3) for about 20 minutes. Garnish with remaining sage. Tomato salad tastes good with it
