Peel the onion and cut into fine slices. Peel and wash the carrots and cut them into thin sticks.
Heat the oil in a large frying pan. Fry the uncooked tortelloni, onion and carrots over medium heat for 6-8 minutes while turning.
Peel and finely grate the ginger. Add to the tortelloni with the tomatoes and bring to the boil briefly. Season with salt, pepper and 1 pinch of sugar.
