Creating Italian Chicken Pastina Soup is straightforward. Follow these simple steps to achieve a delightful bowl of warmth:

1. Heat the Oil: In a large pot, heat the olive oil over medium heat.
2. Sauté the Vegetables: Add the chopped onion, garlic, carrots, and celery. Sauté for about 5-7 minutes until the vegetables become tender.
3. Add Chicken and Broth: Pour in the chicken broth and add the chicken breasts. Bring the mixture to a boil.
4. Season the Soup: Add the dried oregano, thyme, salt, and pepper. Reduce the heat to a simmer.
5. Cook the Chicken: Allow the chicken to cook for about 15-20 minutes, or until it is cooked thoroughly and reaches an internal temperature of 165°F (75°C).
6. Remove and Shred the Chicken: Take the chicken breasts out of the pot and let them cool slightly. Shred the chicken into bite-sized pieces.
7. Add Pastina: While the chicken cools, add the pastina to the simmering broth. Cook according to package instructions, usually about 5-7 minutes.
8. Return the Chicken: Stir the shredded chicken back into the pot along with any chopped spinach or kale if desired. Allow it to warm through for a couple of minutes.
9. Taste and Adjust: Taste the soup and adjust the seasoning with more salt and pepper if needed.
10. Serve: Ladle the soup into bowls, garnish with freshly chopped parsley, and sprinkle with grated Parmesan cheese if desired.

These steps will ensure you create a delicious and comforting Italian Chicken Pastina Soup that will impress your family and friends.
