In a large pot, heat the olive oil over medium heat. Add the chopped onions, carrots, and celery. Sauté for about 5 minutes until the vegetables start to soften.
Stir in the minced garlic, thyme, and oregano, and cook for an additional 2 minutes until fragrant.
Add the chicken breasts, chicken broth, bay leaf, salt, and pepper to the pot. Bring to a boil.
Once boiling, reduce the heat and let it simmer for 20-25 minutes, or until the chicken is cooked through.
Remove the chicken breasts from the pot and shred them using two forks. Return the shredded chicken to the pot.
Add the egg noodles and let the soup simmer for another 10 minutes, or until the noodles are tender.
Taste and adjust seasoning with additional salt and pepper if necessary. Remove the bay leaf before serving.
Serve hot, garnished with freshly chopped parsley or dill.
