Boil 2 eggs hard in about 10 minutes. Soak the rolls in cold water. Peel and finely dice onions. Drain the eggs, rinse with cold water and peel. Knead minced meat, 2/3 of the onion cubes, squeezed out roll and remaining eggs.
Season with salt and pepper. Form an oval loaf from the mince mixture, pressing hard-boiled eggs into the middle. Place the loaf on a cold rinsed fat pan of the oven and bake in the preheated oven (electric range: 200 °C/ gas: level 3) for approx. 45 minutes.
