Dice the chicken breast into bite-sized pieces and season with a pinch of sea salt and black pepper.
Heat the ghee in a medium pot over medium heat, then add the diced carrots, celery, and onion, sautéing until the onion is translucent.
Add the seasoned chicken to the pot and cook for 3-4 minutes until the exterior is no longer pink.
Pour in the chicken bone broth and bring the mixture to a gentle simmer over medium-low heat.
In a small bowl, whisk together the whole wheat flour, baking powder, dried thyme, and the remaining sea salt and pepper.
Slowly stir the water into the flour mixture until a thick, sticky dough forms.
Using a small spoon, drop marble-sized dollops of the dough into the simmering broth.
Cover the pot with a tight-fitting lid and simmer for 10-12 minutes without lifting the lid to ensure the dumplings steam properly.
Remove from heat once the dumplings are puffed and the chicken is cooked through, then serve warm.
