Combine the chicken, 1 tablespoon of olive oil, 1 tablespoon of jerk seasoning, garlic powder, ginger powder, cayenne powder and salt in a large bowl and toss to coat well.
Heat the remaining tablespoon of oil in the Instant Pot insert using the sauté function. When the oil is hot, add the chicken and cook for 1 minute, stirring to brown all surfaces.
Cancel the sauté function and deglaze the bottom of the insert with a few tablespoons of chicken stock, scraping with a wooden spoon to make sure nothing is stuck.
Add pasta on top of the chicken, then pour in the chicken stock. Use a spoon to gently press the pasta down, making sure it is fully submerged.
Place the lid on, turn the valve to sealing, and set for manual pressure/high pressure for 4 minutes. When done perform a quick pressure release.
Open the lid and check the amount of liquid remaining. If there is too much liquid in the bottom of the pot, remove some before continuing.
Stir in the remaining Jerk seasoning, bell peppers, heavy cream, and parmesan cheese. Close the lid and let it sit for about 7 minutes so the peppers soften and the cheese melts.
Garnish, serve, and enjoy.
