Heat the oil in a large pot over medium-high heat.
Add the onion, carrots, celery and garlic and saute for 5 minutes.
Sprinkle in the flour and stir.
Add the oregano, thyme, poultry seasoning and Creole seasoning and cook for 1 minutes.
Add the chicken broth and potato and salt to taste. Bring to a boil then reduce to a simmer and continue simmering for 15-25 minutes or until the potato starts to get tender (depending on how you want it, you might want to keep a little 'bite' to your potatoes).
Stir in the remaining ingredients and cook until the noodles are tender, about 10 minutes.
