Sauté onion and garlic in it. Add tomato paste and sauté briefly while stirring. Add oregano, grated tomatoes and cherry tomatoes and let everything simmer for about 10 minutes. Season to taste with salt, pepper and sugar
Drain the mozzarella. Dice mozzarella and Talleggio finely. Mix both with cream cheese and season with pepper. Fill the pasta with the cheese cream. Spread about half of the pasta close together in a large, greased casserole dish.
