Step 1

To make the tomato sauce, heat the oil in a large saucepan over medium heat. Cook the onion, garlic, carrot and celery, stirring often, for 6 minutes or until soft. Add the wine. Cook for 1-2 minutes or until reduced by half. Add the passata, bay leaf, sugar and oregano. Season with salt and pepper. Bring to the boil. Reduce heat to low. Simmer for 30 minutes. Set aside to cool. Remove and discard the bay leaf. Use a stick blender to blend until smooth. Stir in the vinegar.

Step 2

Heat half the oil in a large frying pan over medium heat. Cook half the chicken for 3-4 minutes each side or until golden and cooked through. Repeat with the remaining chicken.

Step 3

Pour the tomato sauce over the base of a large baking dish. Place the chicken, in a single layer, on top of the sauce.

Step 4

Preheat oven to 200°C. Top the chicken with pancetta and mozzarella. Bake for 25 minutes. Top with the basil.
