For the sauce, peel and chop the onions and garlic. Wash the herbs and chop the leaves or needles finely. Heat oil in a pan. Fry the minced meat until crumbly. Add onions, garlic, herbs and tomato paste and sauté briefly. Stir in tomatoes and juice. Season with salt, pepper, paprika, 1 pinch of sugar and some cinnamon. Coarsely chop the tomatoes with a spatula, bring everything to the boil and simmer open for about 15 minutes. Let the sauce cool down.
Meanwhile cook the macaroni in boiling salted water according to the instructions on the packet. Drain, rinse with cold water and allow to drain. Grate cheese and mix half of it with the pasta.
For the béchamel, heat butter in a pot. Dust with flour and sauté until light brown. Deglaze with 400 ml water and milk. Stir in the stock and simmer for about 3 minutes. Season the sauce with salt, pepper and nutmeg. Take the pot off the stove. Whisk eggs and 2 tbsp. water and stir into the béchamel (do not boil any more!).
Grease a large casserole dish (approx. 20 x 30 cm; approx. 4.5 l capacity) well. Put half of the macaroni into the dish. Approx. 1⁄4 Spread béchamel and half of the chopping sauce on top. Then cover with the remaining macaroni. First spread the rest of the sauce, then the rest of the béchamel. Sprinkle the rest with cheese. Bake in a hot oven (electric cooker: 200 °C/circulating air: 175 °C/gas: see manufacturer) for 45-50 minutes.
