Creating Greek Lemon Chicken Soup can be straightforward if you follow these simple steps:

1. Cook the Chicken: In a large pot, bring the chicken broth to a boil. Add the chicken breasts and cook for about 15 minutes until fully cooked. Remove the chicken and set aside to cool.
2. Sauté Vegetables: In the same pot, add the onion, garlic, carrots, and celery. Sauté for about 5 minutes until the vegetables are tender.
3. Add Orzo: Stir in the uncooked orzo pasta and let it cook for about 10 minutes, or until al dente.
4. Shred the Chicken: While the orzo cooks, shred the cooled chicken into bite-sized pieces.
5. Combine Ingredients: Return the shredded chicken to the pot. Add oregano, salt, and pepper. Stir to combine.
6. Make the Avgolemono Sauce: In a separate bowl, whisk the eggs and lemon juice together until well combined.
7. Temper the Eggs: Gradually add a ladle of hot broth from the pot into the egg mixture, whisking constantly to temper the eggs.
8. Combine with Soup: Slowly pour the tempered egg mixture back into the soup, stirring gently. Make sure the soup is off the heat to prevent curdling.
9. Serve: Taste and adjust seasoning if necessary. Ladle the soup into bowls and garnish with fresh parsley.
