Add olive oil, onions, celery, carrots, spices, and bay leaf to a large pot or Dutch oven. Stir to combine, and cook over medium-low heat for 5-6 minutes to soften vegetables, not brown them.
Add chicken, broth, water, and chicken base, and stir to combine, scraping any brown bits off the bottom of the pot.
Over medium-heat bring the mixture to a simmer. This should take for 4-5 minutes. Do not bring it to a boil.
Turn the heat to medium-low, cover, and simmer for about 20 minutes or until the chicken is done. Transfer the chicken to a plate, cover, and let rest.
Cover the pot, and bring to a boil.
Add noodles and cook 1-2 minutes short of the recommended cooking time.
While the noodles cook, shred or chop the chicken into bite-sized pieces. Set aside.
When the noodles are done cooking, remove the pot from the heat. Let cool for 1 minute. Remove and discard the bay leaf, and then add the chicken.
Add salt and pepper to taste and garnish with fresh parsley.
