In a large pot over medium heat add the olive oil. Then add the reserved chicken parts and cooked until browned, about 7-10 minutes. Turn the chicken occasionally so it browns on all sides.
Add the chopped onion, fennel, carrots, green seasoning, and garlic. Sautee for 4-5 minutes or until the onion begins to brown and looks translucent.
Pour in the broth. Add the seasonings for the soup and thyme. Cover and simmer on medium low for 20-25 minutes or until the chicken is tender. Once the chicken is tender you can leave the chicken on the bone or gently shred it with a fork and add it back to the soup. If the broth in the soup is low, add additional boiling water.
If desired, sift the cock soup mix packet over a strainer to remove the macaroni noodles. Add the cock soup mix seasoning to the pot. Then add the rest of the vegetables for the soup except the spinach. Check the seasoning and adjust to taste. Cover and simmer for 20 minutes or until the winter squash is tender. The squash may begin to break apart a bit and color the broth light orange, but that is okay! It will slightly thicken the soup.
Remove the lid and take out the thyme stems. Add the spinach and simmer until its wilted.
Enjoy!
