Boil a pot of water and cook the gluten free penne pasta according to the package directions. Drain and set aside.
Meanwhile, cook the chicken breasts: I like to do this by broiling them which only takes 10 minutes: Preheat your broiler. Line a baking sheet with foil and make sure your oven rack is positioned about 4 inches below the broiler.
Cut your chicken breasts in half horizontally to form 4 thinner breasts. Season on both sides with salt, pepper, and garlic powder. Spray the baking sheet with olive oil or avocado oil then lay the chicken breasts out in a single layer. Spray the tops of the chicken breasts. Broil then for 3-4 minutes on the first side, then flip and cook for an additional 3-4 minutes until the internal temperature has reached 165 degrees. Remove the pan from the oven and wrap the foil around the chicken breasts to keep them warm.
Heat the 1 tbsp olive oil in a large pot or dutch oven over medium high heat.
Add in the onions and garlic and saute for 3-4 minutes until fragrant and beginning to soften.
Add in the vodka and use a wooden spoon to scrape any browned bits off the bottom of the pot.
Pour in the crushed tomatoes, tomato sauce, chicken broth, salt, and Italian seasoning. Bring to a boil, then reduce the heat and let the sauce simmer for 10 minutes.
Turn off the heat, and add in the Nutpods (or half & half) and the parmesan cheese and stir to combine. Dice up the chicken and add it into the pot along with the cooked pasta. Stir everything to combine.
Season with salt and pepper to taste. Serve topped with fresh parsley and more parmesan cheese, if desired.
