Place the chicken thighs into the slow cooker, then add the pepperoni, sun-dried tomatoes, pesto, garlic oil, oregano, paprika and half of the chicken stock (500ml).
Pop the lid on and cook on high for 1 hour, then add the pasta and spinach, followed by the rest of the stock. Mix it in and allow to cook for about ten minutes with the lid on.
Just before the ten minutes is up (when the pasta is ALMOST cooked) stir in the cream cheese and cornflour mixture.
Finish optionally with grated parmesan and spring onion greens.
