In a heated frying pan with vegetable oil, fry the vegetables until golden brown.
Combine the fried vegetables with the minced meat, add salt and mix thoroughly.
Place the dry pasta in a frying pan, leaving a little space between the nests, and place a ball of minced meat in each.
Mix tomato paste with water and pour the mixture over the spaghetti nests until the liquid covers them.
Cover the pan with a lid and place it on high heat. As soon as the tomato mixture boils, reduce the heat to low and cook for another 20 minutes.
