Halloumi is a semi-soft cheese, somewhat similar to block feta cheese or softer paneer ... even better, on a lamb burger), you should slice your halloumi quite thinly before grilling, otherwise ...

These lamb burgers are packed with the salty, savoury flavours of anchovy, gherkin and capers, with a little ball of sheep’s cheese as a surprise inside. Preheat the oven to 180C/350F/Gas 4.
