1. Bring a large saucepan of water to the boil. Add the spinach to the boiling water and cook for 30 seconds. Remove the spinach and refresh in ice water. Drain and squeeze all the liquid from the leaves with your hands, getting as much out as possible, then finely chop.

2. In a large bowl put the spinach, pork mince, eggs, breadcrumbs and three tablespoons of the olive oil, season with sea salt and freshly ground black pepper, and mix until well combined. Roll the pork mixture into balls about the size of a golf ball.

3. Heat the remaining oil in a deep saucepan over medium heat. Cook the meatballs in batches for two to three minutes, until light golden brown on the outside, then remove and set aside. They will finish cooking in the sauce.

4. For the sauce, add onion, garlic and sea salt to the pan and sweat for three to five minutes. Add the tomato paste and chilli flakes and cook for another minute, then pour in the chopped tomatoes and stock. Bring to the boil, then reduce the heat and add the meatballs. Simmer gently for 20 minutes, until they are cooked through. Give a grind of pepper and stir in the chopped coriander. Serve immediately.
