Break through 1x macaroni and put into boiling salted water. Cook for about 8 minutes, then drain, quench and drain well in a sieve. Meanwhile peel and roughly dice the onion.
Peel and finely chop the garlic. Crumble the minced meat. Heat the oil in a pan and fry the minced meat thoroughly while turning. Add onion, garlic and oregano and fry briefly. Add tomato paste and stir in.
Dust with cinnamon, add tomatoes and let it boil down for about 12 minutes at medium heat. Season to taste with salt, pepper and sugar. In the meantime whisk eggs and season with salt, pepper and nutmeg.
Mix the pasta, 3/4 of the cheese and eggs. Put half of the pasta in a well greased casserole dish, spread the minced meat mixture on top. Pour the rest of the noodles on top and pour the remaining beaten eggs over it. Sprinkle with remaining cheese and bake in a preheated oven (electric oven: 200 °C/ gas: level 3) for about 40 minutes.
If necessary, cover the casserole after half the baking time. Remove from the oven and serve garnished with oregano as desired.
