Dice the chicken breast into bite-sized pieces and finely chop the carrots, celery, and onion.
In a large pot, sauté the onion, carrots, and celery with a splash of bone broth over medium heat until the vegetables are softened and fragrant.
Add the diced chicken, garlic powder, sea salt, and black pepper to the pot, searing the chicken until it is no longer pink on the outside.
Pour in the remaining chicken bone broth and bring the mixture to a gentle simmer.
While the broth simmers, prepare the dumpling dough by whisking together the cassava flour, baking powder, fresh thyme, and fresh rosemary in a small bowl.
Melt the ghee and stir it into the flour mixture along with the almond milk until a thick, cohesive dough forms.
Using a small spoon, drop rounded portions of the dough into the simmering broth, ensuring they are spaced apart.
Cover the pot with a tight-fitting lid and cook for 10-12 minutes without lifting the lid, allowing the dumplings to steam and fluff up.
Once the dumplings are firm and the chicken is fully cooked, ladle the soup into a bowl and serve immediately.
