Add wine, passata, sugar, bay leaves and onion mixture. Season with pepper and stir to combine. Bring slowly to the boil, then reduce heat to low and cook, uncovered, stirring occasionally, for 1 hour.
• Cook pasta in a large saucepan of rapidly boiling salted water following pack instructions or until al dente. Drain. Add 2 large spoonfuls of sauce and toss to combine. 5. Serve pasta topped with remaining sauce, with parmesan on the side.
