Making Chinese Chicken Noodle Soup is straightforward with these easy-to-follow steps:

1. Prepare the Chicken: In a large pot, bring the chicken broth to a boil. Add the chicken breasts and cook for about 20 minutes or until thoroughly cooked.
2. Shred the Chicken: Once cooked, remove the chicken from the pot, let it cool, and then shred it into bite-sized pieces.
3. Sauté Aromatics: In the same pot, heat the sesame oil over medium heat. Add the sliced onion, minced garlic, and grated ginger. Sauté for about 2-3 minutes until fragrant.
4. Add Vegetables: Stir in the sliced carrots, celery, and diced bell pepper. Cook for another 5 minutes until they begin to soften.
5. Add Broth and Noodles: Return the shredded chicken to the pot. Pour in the chicken broth and bring to a gentle boil. Add the egg noodles and let them cook until tender, about 6-8 minutes.
6. Incorporate Spinach: Once the noodles are tender, stir in the baby spinach (or bok choy) and let it wilt for about a minute.
7. Season: Add soy sauce, and season with salt and pepper to taste. Mix well to combine all flavors.
8. Serve: Remove from heat and ladle soup into bowls. Garnish with chopped green onions and fresh cilantro if desired.

These simple steps will guide you through a delightful cooking process, leaving you with a fragrant and delicious soup that is sure to impress.
