Cornish New potato and harissa-marinated halloumi skewers

These delicious potato and halloumi kebabs are the perfect option for a vegetarian starter or main course.

1Chop the halloumi into roughly 2.5 cm cubes. Crush the garlic then combine with the harissa, 2 tbsp of the olive oil and the juice of half the lemon in a bowl. Add the halloumi and toss to combine. Marinate for one hour, or overnight.
2Prepare the potatoes by rubbing off any loose skin under a tap. Chop any larger potatoes in half. Half-fill a saucepan with cold water then add the potatoes. Place over a high heat and bring up to the boil, then allow to boil for 7 minutes before draining. Allow to cool slightly while you prepare the remaining vegetables.
3Preheat the barbecue or put a griddle pan over a high heat. Slice the onion into wedges and the courgette into 1 cm rounds, then cut down the middle to make half-moons. Toss the courgette and Cornish New Potatoes in a bowl with the remaining 1/2 tbsp oil and season to taste.
4Thread the Cornish New Potatoes, red onion, courgette and halloumi, reserving any loose marinade, onto the skewers. Barbecue or griddle for 12-15 minutes, turning every few minutes, until everything is golden and lightly charred and the potatoes are cooked through.
5Mix the yoghurt with the leftover harissa marinade and serve alongside the skewers, with a scattering of roughly chopped coriander leaves, the remaining lemon half sliced into wedges, and a side salad, if liked.
