Preheat your oven to 160C fan/ 325F / Gas 4
In your heavy bottomed casserole dish (hob proof) put your olive oil and turn on the heat to medium
Next add your onion, ginger, garlic, lamb and fry for 5 minutes, stiring
Next add your Chilli Powder, Turmeric, Garam Marsala and mushrooms, stir and fry for a further 5 minutes, stiring
Then add your rice and stock and  coriander leaves give it all a good stir and season with salt and pepper
Pop the lid on your casserole (or cover tightly with foil) and pop in the centre of the oven for 30 minutes
Remove and stir, making sure your rice is tender.If it looks a bit dry ad a splash more water
Return the lid and leave to stand for 10 minutes on the side (do not put it back in the oven)
Then simply serve with a dollop of yoghurt and fresh coriander leaves - yum!
