Heat the olive oil in a large pot over medium heat. Add the onion, garlic, carrots, and celery. Sauté for 5 minutes until softened.
Stir in the thyme, oregano, and bay leaf. Cook for an additional 1-2 minutes until fragrant.
Pour in the chicken broth and bring to a boil. Reduce the heat to a simmer and let it cook for 15 minutes.
Add the shredded chicken and gluten-free noodles. Cook until the noodles are tender, about 8-10 minutes.
Stir in the spinach or kale and cook for another 2 minutes until wilted. Season with salt and pepper to taste.
Serve hot, garnished with fresh parsley and a squeeze of lemon juice for added brightness. Enjoy this cozy, nutrient-packed bowl!
