Add the chicken stock to a large pot over medium high heat and bring to a simmer. Add in the carrots and celery and continue simmering for 10 minutes.
Add in the chicken and cauliflower rice and cook for another 8-10 minutes. Serve with a garnish of fresh parsley.
Notes
The carrots are optional, so if you want to stay super low carb, you can certainly omit them.*Macros will vary greatly, depending on the chicken stock that you use. If you are concerned about nutritional information, please feel free to use an app like MyFitnessPal to calculate your macros, based on the chicken stock that you use.
