Mix well and simmer for a couple of minutes.
Then, add vegetables to half -finished meatballs.
Cover with a lid and cook all together until cooked. This will be noticeable even visually: the water will evaporate slightly, and the meatballs in the vegetable sauce, which increased in size, thanks to the drawing, will remain in the pan. If you doubt, you can taste one little thing, evaluating its taste and degree of readiness.
