To make the tomato sauce: Place the passata, thyme/oregano leaves and garlic in a sauce pan. Bring to the boil then reduce the heat and simmer for 8 minutes.
To prepare the aubergine and chops: Heat a griddle or frying pan. Brush a little oil over the slices of aubergine, season and add them to the pan. Cook for a minute or two on each side. Set aside and keep warm. Add a little more oil to the pan then season the pork chops and add them to the pan. Cook over a high heat until golden – about two minutes on each side.
To assemble: Remove the sprigs of thyme from the tomato sauce. Spoon a layer of tomato sauce into a 15cm x 25cm baking dish, then sprinkle over a handful of cheese. Add the pork chops and then the aubergine slices. Spoon over another layer of tomato sauce. Sprinkle over the rest of the cheese and breadcrumbs. Tear over the mozzarella.
To cook: Bake at Gas Mark 4, 180°C (350°F) for 25 minutes, or until golden, crisp and bubbly.
Serve with a salad.
