Halloumi Marinade

Finely grate the zest of the lime into a shallow dish, then squeeze its juice into a separate bowl. Whisk 6 tbsp of olive oil into the zest, then add half of the lime juice, together with the chillies, herbs, garlic and black pepper. Cut the block of halloumi into evenly sized, fairly thick slices (so that they won’t fall apart on the barbecue), then add the slices to the shallow dish, turning them to coat them completely. Leave to marinate for several hours before cooking.
