Karens Chicken Noodle Soup

Karen's EASY But So Good -I'm talking the best- Creamy Chicken Noodle Soup Ever!!
(this recipe is doubled- it makes about 5-6 qts of soup)
6 Tblsp. Butter
2 Cups chopped onion
2 Cups chopped celery
2 Cups sliced mushrooms
Saute until everything is tender in a soup pot.
(I added 1 cup carrots diced also just because it seemed like the right thing to do & I didn't have that much celery )
Now add:
2 Cups cooked chicken -(I added 3 boiled chicken breast diced)
4 Cups of Noodles
Cover everything with water- just barely. I used the water from boiling the chicken & a little more.
Now add:
4 chicken bouillon cubes
2 cans of cream of chicken soup
Bring to a boil & simmer until the noodles are tender! Salt & pepper to taste.
ENJOY!
