Add the spinach to the pan and allow to wilt. Pour milk and cream into the pan and mix. Add salt, oregano, chilli flakes and black pepper powder and mix well. Turn heat down to low. Wait until the sauce thickens slightly – 1-2 minutes. Add three-fourth of the parmesan cheese to the pan. Mix and switch off. Add back chicken, tomato to the pan. Add pasta also and gently fold in. Transfer to plates and top with remaining parmesan cheese. Serve warm. Enjoy!
