Directions

1. In a large bowl, combine ground chicken, Panko, Parmesan, oregano, basil, parsley, garlic powder and red pepper flakes, if using; season with salt and pepper, to taste. Using a wooden spoon or clean hands, stir until well combined. Roll the mixture into 3/4-to-1-inch meatballs, forming about 25-30 meatballs.
2. Heat 1 tablespoon olive oil in a large stockpot or Dutch oven over medium heat. Add meatballs, in batches, and cook until all sides are browned, about 2-3 minutes. Transfer to a paper towel-lined plate; set aside.
3. Add remaining 1 tablespoon oil to the stockpot. Add garlic, onion, carrots and celery. Cook, stirring occasionally, until tender, about 3-4 minutes. Stir in thyme and rosemary until fragrant, about 1 minute.
4. Whisk in chicken broth, bay leaf and 2 cups water; bring to a boil. Stir in meatballs; reduce heat and simmer until meatballs are cooked through, about 10-12 minutes. Stir in zucchini noodles during the last 3-5 minutes of cooking time.
5. Stir in lemon juice; season with salt and pepper, to taste.
6. Serve immediately, garnished with parsley, if desired.
