Peel, trim and chop 2 carrots, 2 celery stalks, and 1 large onion then set aside.
Heat olive oil in a dutch oven or soup pot, then add the carrots, celery, onion, and the garlic.
Pour the chicken broth and water into the pot, then stir in the turmeric, oregano, red pepper flakes, salt, and pepper. Bring to a boil then add the chicken breasts.
Cook for 15 minutes, then remove the chicken from the pot and add the orzo pasta. The pasta will be done in 7-8 minutes.
Meanwhile shred the chicken, then return it to the soup pot. Simmer for 5 more minutes, then transfer the soup to a soup service bowl.
Stir in the chopped parsley and scallions. You can also add lemon juice to this soup at this point if you like. Serve and enjoy.
