Sauté celery, carrots, garlic and onions in butter for about 7 minutes, or until vegetables begin to soften. Stir intermittently.
While vegetables are sautéing, in a separate pan, heat olive oil and cook chicken breast with pepper, salt, oregano, and basil for 10-12 minutes or until the chicken is cooked through.
In a pot, add chicken broth and cooked noodles (keep noodles separate and add to individual bowls if you don't plan to eat all the soup in one sitting). Then add chicken and vegetables.
Allow to simmer for 10 minutes prior to serving.
Notes
To save time, feel free to use a rotisserie chicken.
If you plan on making this soup recipe in advance, keep the noodles separate so they don’t get soggy.
To freeze, let your soup cool completely and keep it in the freezer for up to four months.
