Warm the butter and olive oil in a Dutch oven over medium heat. Add the celery, carrots, and onions, and saute for 10 minutes.
Stir in the garlic and cook for one minute, then add the flour and cook for another minute.
Pour the chicken broth into the pot and stir until the flour dissolves. Add the salt, pepper, basil, oregano, dill, and chicken breasts.
Bring the soup to a boil. Then, reduce the heat and cover the pot with the lid slightly ajar for 15 minutes.
Remove the lid and stir in the stelline pasta. Cook for 5-7 minutes or until the pasta is tender.
Take the chicken out of the pot; shred or cut it up, depending on your preference.
Return the chicken to the pot, stir in the fresh lemon juice, and taste and season with salt.

Enjoy my take on Lemon Chicken Orzo Soup from Salt and Lavender, showing you how to use stelline pasta as a substitute for orzo in a recipe - kind of like chicken noodle soup. Arborio rice is another tasty option.
