Peel and dice the onion. Peel the carrots and also finely chop them. Pluck the leaves of the rosemary from the stem and cut into small pieces. Also dice the canned tomatoes.
Heat the oil in a larger saucepan and fry the minced meat in it. Add the onion and carrot cubes and season well with the spices and rosemary. Then add the tomato cubes and the tomato paste as well as the remaining tomato juice from the can. Pour in the vegetable stock and let it simmer for about half an hour. When the carrots are done, season again - if necessary - with ketchup, soy sauce and salt.
Serve with spaghetti or macaroni and parmesan. A green or mixed salad goes well with it.
