In a large pot add the potatoes, water, fresh lemon (prick with a knife a few times) and garlic salt and bring to the boil for 5 minutes.

Next prepare your chicken. Stuff the chicken with the preserved lemon, fresh lemon and a handful of chorizo. Then rub with some olive oil and garlic salt.

Then layer the potatoes in tray, sprinkle with salt, add the onions and garlic and top with the chicken, and chorizo pieces. Sprinkle with some cracked black pepper.

Remove the chicken and let it rest, continue to cook the potatoes until they crisp up. About another 20 minutes or so.
