For the noodles, bring 3-4 l salted water (approx. 1 teaspoon salt per litre) to the boil. Peel onion and garlic, dice finely. Heat the oil in a large pan. Fry the minced meat in it until crumbly. Fry the onion and garlic briefly.
Stir in tomato paste and sweat briefly. Add tomatoes and 1/8l water, bring to the boil. Cover and simmer for 10-15 minutes.
Meanwhile cook the noodles in boiling water according to the instructions on the packet. Wash the thyme, shake dry and pluck off the leaves. Roast the toast bread in a toaster, spread a thin layer of butter on it and then dice it finely.
Stir the thyme into the sauce. If the sauce has boiled down too much, stir in some pasta water (approx. 4 tablespoons). Season the sauce to taste with salt, pepper and 1 tsp. sugar. Drain the noodles, put them back into the pot and mix with the sauce.
Serve sprinkled with croutons.
