Season the diced chicken with the salt and pepper.
Set the instant pot to a 10 minute saute and add the oil. Once heated, add the chicken to the instant pot. Brown the chicken pieces for about 5 minutes, then flip and brown the other side for the remaining 5 minutes of saute time.
Stir in the dried basil, oregano, and pasta. Pour the broth over the pasta.
Secure the lid and set to high pressure for 5 minutes. Let the pressure release naturally for 5 minutes.
Stir in the sun dried tomatoes and 2 tbsp of their oil, spinach, and parmesan. Let sit for 10 minutes with the lid on, then stir again.
Scoop the pasta out of the pot and enjoy with extra parmesan if desired.
