Dice the chicken breast into small, uniform bite-sized pieces and season with a portion of the sea salt and black pepper.
Heat the ghee in a medium pot over medium heat and sauté the chicken until it is golden brown on all sides.
Add the diced onion, sliced carrots, and sliced celery to the pot, cooking for 5 minutes until the vegetables begin to soften.
Pour in the chicken broth and add the dried thyme, bringing the liquid to a gentle simmer over medium-low heat.
In a small mixing bowl, whisk together the whole wheat flour, baking powder, and the remaining sea salt.
Stir in the Greek yogurt and water until a soft, slightly sticky dough forms.
Using a small spoon, drop rounded tablespoons of the dough directly onto the surface of the simmering broth.
Cover the pot with a tight-fitting lid and steam for 10 minutes without opening the lid to ensure the dumplings become light and airy.
Remove from heat and garnish with freshly chopped parsley before serving in a shallow bowl.
