Cheater Chicken Noodle Soup

I had a sick family so needed to make a quick lunch of chicken noodle soup. Everyone liked it. Cheater because I bought a roasted chicken at the grocery store. I based this on a recipe I found online but can't find it anymore. This is from memory.
1/16/25 used Italian chicken pieces from jumbo, chicken bouillon cubes, half a small yellow onion, sage, bay leaves, parsley, dash of fish sauce. Cooked egg noodles separately to be able to freeze leftovers.

• chicken, roasted
• 4 c vegetable broth (or more)
• egg noodles
• celery (optional)
• carrots, cubed
• salt
• pepper
• garlic (instead of onion)
• thyme
• 1 T butter

1. Saute minced garlic in butter.
2. Add carrots (and celery). 
3. Add broth and bring to boil. Season with salt, pepper and thyme.
4. Add chicken pieces.
5. Add egg noodles to cook through (OR cook separately so that the soup sans noodles can be frozen and used later).
6. Simmer for 20 min.
7. Serve with bread.
