Place the oil and ground coriander in a small bowl and mix together, then season well. Toss the pork chops, sweet potatoes and garlic in the oil and spread out on a shallow baking tray. Place in a preheated oven, 220°C (425°F), Gas Mark 7, for 10 minutes.
Meanwhile, stir together the honey and lime rind and juice in a bowl. Turn the meat and sweet potatoes over, then drizzle over the honey sauce. Return to the oven for a further 5–10 minutes until golden and cooked through.
Scatter over the chopped coriander, chilli and spring onions and serve with lime wedges.
