Start cooking classic Italian Bolognese. Pour vegetable oil into a deep frying pan. Put onion and carrot. Fry for 4 minutes. Add celery, stir and fry for another 3-4 minutes. Put minced meat and salt it. Stir and fry until done for 15 minutes.
Continue cooking Italian spaghetti bolognese. Add tomato paste, tomatoes and greens to the minced meat and vegetables. Add ground black pepper and mix well. Pour in a glass of meat broth. Mix again. Cover with a lid, reduce heat and simmer for 25 minutes. Add chopped garlic. Cover again and simmer for another 5 minutes.
Prepare the pasta. Pour water into a saucepan and bring it to a boil. Add salt. Put the spaghetti in the saucepan and cook for 10 minutes. Drain in a colander. No need to rinse. Put the spaghetti back in the saucepan, add vegetable or olive oil. Stir.
