For the tomato sauce, clean or peel the soup greens. Peel onions and garlic. Dice everything finely. Heat 2 tablespoons of oil in a saucepan. Fry the soup greens, half onions and half garlic. Sauté 2 tbsp. tomato paste briefly. Add the tomatoes and juice and chop with a spatula. Bring to the boil and simmer for about 5 minutes. Stir in 800 ml water, bring to the boil again. Season sauce with salt, pepper and 1 pinch of sugar.
For the roast, soak rolls in water. Wash and chop the herbs. Dice mozzarella finely. Chop, squeezed out roll, 1 tbsp. tomato paste, eggs, herbs, mozzarella, remaining onions and garlic, 2 tsp. salt and pepper each, knead well.
Form an oval roast from the mince. Heat 2 tablespoons of oil in a large frying pan. Brown the roast on each side. Mix the noodles and tomato sauce and spread in a large casserole dish. Place the roast on top (see tip) and cover everything with aluminium foil. First braise in the preheated oven (electric cooker: 200 °C/circulating air: 180 °C/gas: see manufacturer) for about 1 hour. Remove the foil and cook for approx. 15 minutes until open.
After all, the roast should not sink too deep into the sauce. In addition, the volume of the pasta triples during braising.
