Put vegetables, water, chicken bouillon, pepper, Italian seasoning and bay leaves in a large pot.
Heat over medium high and bring to a boil.
Reduce heat slightly and allow to simmer for about 25 minutes. (If your chicken wasn't cooked, you could cook it in the water here)
Add chicken, and noodles.
Cook for about 10 minutes (or however long your noodles say to cook for)
Remove bay leaves.
Combine flour with 3 TBS water in a small bowl.
Add flour paste to soup to help thicken broth a little bit. Allow to cook for a couple minutes to thicken.
Enjoy this soup hot off the stove with a small side of bread or crackers!
