Add the chicken breast to the crock pot in a single layer, not overlapping.
Pour chicken stock in the bottom of the crock pot. Top the chicken breasts with the julienned sun-dried tomatoes.
Pour the parmesan garlic sauce on top of the chicken, and layer the cream cheese on top of the sauce.
Put the lid on the crock pot and cook the chicken on high for about 2 to 2 ½ hours, until fully cooked through. The chicken is done when it reaches a safe internal temperature of 165 degrees F.
Using two forks, shred the chicken and stir well to bring the sauce and chicken together. Turn the crock pot down to warm, and let the shredded chicken and sauce meld for a few minutes while you make the pasta.
Cook the pasta according to package instructions, and drain. Add the cooked pasta to the crock pot with the chicken, and stir well to coat the pasta in sauce.
Taste the pasta and season with salt and pepper, to taste. Top each serving with 1-2 tablespoons freshly shredded Parmesan cheese, and enjoy!
