cut the potato into 1/2 inch cubes, and add to a large pan of water with salt to taste, and 1/2 tsp turmeric. Bring to the boil and boil for 7 minutes
Meanwhile, cut the halloumi into chunks. Fry the chunks until they start to catch, then add the diced onion and cook over a low heat until it softens.
Add the stock cube, garlic, ginger and spices and stir to ensure everything is coated.
Add the tomatoes, coconut milk, chickpeas and the parboiled potatoes
Stir well, cover, reduce the heat and cook for about 15 minutes. This is a good time to then cook the rice
