Preheat the oven to gas 6, 200°C, fan 180°C. Toss the potato chunks in the oil, then add the cumin seeds, chilli and turmeric. Mix well until the potatoes are coated and transfer to a baking sheet. Roast in the oven for 30-35 minutes, until the potatoes are golden and tender.
Meanwhile, rub the pork chops with a drop of oil and massage the curry powder into the flesh and skin. When the potatoes have been in the oven for 15 minutes, heat the remaining oil in a large nonstick frying pan and fry the pork chops for 5-7 minutes each side, until cooked through and golden.
In a bowl, mix the tomatoes, cucumber, onion, coriander and season. Serve with the pork chops, cumin potatoes and some mango chutney on the side, if you like.
