Cook pasta in salted boiling water according to package direction until al dente. Once cooked, drain (reserve 2 tbsp pasta water for later) and set aside (drizzle with olive oil so that pasta won’t stick together).
Cut chicken breast into cubes and place in a bowl. Season chicken with 1/2 tbsp olive oil, finely minced garlic, Italian seasoning, smoked paprika, salt and pepper.
Heat the remaining 1/2 tbsp olive oil in a large nonstick skillet. When hot, add seasoned chicken and cook though on both sides, until tender.
Once chicken is cooked, add to the skillet chopped sun-dried tomatoes, baby spinach and a couple tablespoons of pasta water. Cover with a lid and cook over medium heat for a couple of minutes, until spinach is cooked.
Add to the skillet cooked pasta, Parmesan cheese and give it a good stir. Taste and adjust with more salt and pepper if necessary.
Serve healthy chicken pasta with a sprinkle of Parmesan cheese more and chili flakes, if you desire.
