In a large frying pan, heat 1 tbsp of sun dried tomato oil. Add the thinly sliced chicken breasts, red pepper, and a pinch of salt and pepper. Fry over high heat for about 5 minutes, then set aside.
Deglaze the pan with a splash of chicken stock. Reduce the heat to medium/low, then add the sun-dried tomatoes, smoked paprika, red pepper flakes, tomato puree, and garlic. Fry for about 5 minutes, adding a splash of stock as needed to prevent burning.
Add the cheese tortellini and the remaining chicken stock to the pan. Return the cooked chicken and red pepper to the pan as well. Cook for 8-10 minutes, stirring occasionally.
In the final 2 minutes of cooking, add the spinach, crème fraîche, and grated Parmesan or Pecorino.
Once the sauce has thickened and the tortellini is al dente, serve the dish with an extra sprinkle of Parmesan, a pinch of red pepper flakes, and torn fresh basil.
