Pour one tablespoon of olive oil into a pot or large skillet over medium heat. Add chicken pieces and mushrooms and cook until chicken is golden and mushrooms softened, about 8-10 minutes.
Add garlic and tomatoes and cook for one additional minute. Remove chicken mixture and place in a bowl while cooking pasta.
Bring to a boil in the same pot or skillet, 4 cups of water. Add salt and pasta. Cook until al dente, approximately 9 minutes or according to the pasta instructions.
Drain off most of the water, leaving about 1/2 cup in the skillet. Add to the pasta, chicken mixture, basil, pepper, parmesan cheese, and remaining olive oil, toss to combine.
Enjoy!
