On the foil lined sheet pan place all of the chicken and bake for 15-22 minutes or until done depending on the choice of meat.
While the chicken is cooking add the oil, carrots, onion, and celery to a pot and cook until vegetables have softened. Add the stock and rosemary and oregano tied with butcher's twine and reduce to a simmer for 30 minutes. Remove the rosemary and oregano.
In a saucepan cook the pasta according to instructions.
Once the chicken is ready shred or cut add to the soup. Season with salt and pepper to taste. Drain the pasta and add to the soup.
