First up, mix together yoghurt, tandoori masala and lemon juice and marinade your halloumi pieces for an hour or so.
Meanwhile, curry time - very gently fry the onions in the butter until they are soft, brown and caramelised. Add the ginger and garlic and cook for a minute on a higher heat before adding passata. Add the ground spices and cook out and reduce the sauce, then add the coconut cream, cashew cream and real cream. Stir and add the coriander then take off the heat ready for the burger!
Meanwhile, heat up your grill/BBQ if using and grill the halloumi pieces to your liking.
Assemble your burger! Toasted brioche, mango chutney, halloumi, tikka sauce, bombay mix - whatever you like!
