In a small bowl, combine the oil, garlic powder, smoked paprika, and salt for the chicken marinade.
Stir until a smooth paste forms.
Add the diced chicken to the marinade and coat evenly.
Allow the chicken to marinate for approximately 10 minutes while preparing the remaining ingredients.
Heat 1 tablespoon of oil in a large skillet over medium heat.
Add the chorizo sausage and marinated chicken to the skillet.
Cook for 8 to 10 minutes, stirring occasionally, until the chorizo is browned and the chicken is fully cooked.
Remove the cooked chorizo and chicken from the skillet and set aside.
Leave the rendered oil in the skillet to flavor the sauce.
Add the remaining oil to the same skillet, if needed.
Add the finely diced onion and diced orange bell pepper.
Sauté for approximately 7 minutes, or until the onion is translucent and the bell pepper has softened.
Stir in the tomato paste.
Cook for 1 to 2 minutes, stirring frequently, to deepen the flavor of the tomato paste.
Add the tomato sauce and heavy cream.
Stir until the sauce is fully combined and smooth.
Bring the mixture to a gentle simmer.
In a small bowl, whisk together the all-purpose flour and 1/2 cup warm water until smooth.
Slowly pour the flour mixture into the sauce while stirring continuously to prevent lumps.
If the sauce begins to form lumps, briefly remove the skillet from the heat and continue stirring until smooth.
Return the skillet to a gentle simmer.
Add the cooked chorizo and chicken back to the skillet.
Stir until the meat is evenly coated in the sauce.
Simmer for 10 to 15 minutes, stirring occasionally, until the sauce thickens and becomes creamy.
Stir in the garlic powder, smoked paprika, dried oregano, chili flakes if using, black pepper, fresh parsley, and remaining salt as needed.
Taste and adjust the seasoning carefully, as chorizo and cheese may already contain salt.
Add the cooked pasta to the skillet.
Toss thoroughly until the pasta is evenly coated in the creamy chorizo sauce.
Allow the pasta to cook in the sauce for 1 to 2 minutes, if needed, until it reaches the desired texture.
Remove from the heat.
Serve hot with freshly grated Asiago cheese, if desired.
