Bring a large pan of salted water to the boil and cook the cauliflower for 5 mins over a high heat, adding the spinach for the final 2 mins. Drain and set aside.

Heat the oil in a large frying pan or shallow casserole dish and fry the onion over a medium heat for 5 mins. Turn up the heat, add the halloumi, cook for a further 5 mins, then add the garlic, ginger, turmeric and curry powder, and cook for 1 min more. Stir through the rice, cauliflower and spinach to warm everything through, adding 1 tbsp water if it looks a little dry. Season and scatter over the chilli.
