Creating Sicilian Chicken Soup is a breeze when you follow these simple steps:

1. Prepare the Chicken: In a medium pot, boil the chicken breast in salted water for about 15 minutes until cooked through. Remove and let it cool, then shred the chicken using two forks.
2. Sauté Vegetables: In a large soup pot, heat olive oil over medium heat. Add chopped onion, carrots, and celery. Sauté until the vegetables soften, about 5-7 minutes.
3. Add Garlic and Spices: Stir in the minced garlic, dried oregano, and thyme. Cook for another minute until fragrant.
4. Incorporate Tomatoes: Add the canned diced tomatoes, including their juices, to the pot. Stir to combine with the vegetables.
5. Pour in Broth: Add the chicken broth along with the bay leaf. Bring the soup to a boil, then reduce to a simmer for 15 minutes.
6. Add Shredded Chicken: Once the broth is simmering, add the shredded chicken to the pot. Stir well and allow it to heat through.
7. Incorporate Greens: Add the chopped spinach or kale during the last 5 minutes of cooking. This will ensure they are tender but still vibrant.
8. Season and Serve: Remove the bay leaf, then season with salt, pepper, and lemon juice to taste. Give it a final stir before serving.
9. Garnish: Spoon the soup into bowls and sprinkle with fresh parsley for an extra touch.

By following these steps, you’ll create a warm and inviting bowl of Sicilian Chicken Soup that is sure to impress.
