Soak rolls in cold water. Boil 3 eggs in boiling water for about 10 minutes, rinse with cold water and peel. Wash the parsley, shake dry and, except for something to garnish, pluck it from the stalks and chop. Squeeze the bread rolls well. Knead with minced meat, 1 egg and mustard.
Season with salt and pepper. Shape for frying, placing the boiled eggs in the middle. Put them on the fat pan of the oven. Roast in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for about 1 hour
Remove the meatloaf from the fat pan and keep it warm. Pour 150 ml stock into the fat pan, loosen the frying set and pour it through a sieve into a pot. Bring the meat to the boil and thicken with sauce thickener. Serve meatloaf with sauce
