Boil the pasta in salted boiling water until al dente which is about 12 minutes. Then drain and place back in the pot.
While the pasta is cooking, add the olive oil to a pan along with the chicken and its seasonings. Cook for about 8 minutes until the chicken is fully cooked and tender with a nice sear on each side. Set the chicken aside in a bowl.
In the same pan the chicken was cooked in, add the olive oil along with the tomatoes, garlic, and sundried tomatoes. Saute for 5 min or so. Then, add the corn starch and stir.
Add the heavy whipping cream, stock, pesto or paste, and seasonings. Stir and let this simmer until the sauce starts to thicken. Once it starts to thicken which will take a few minutes on medium heat, add the parmesan cheese and stir.
Then, add the chicken back to the sauce and mix together. Pour the sauce onto the pasta and stir. Enjoy!
