Dice the chicken breast into bite-sized pieces and season with a pinch of sea salt and black pepper.
Heat the olive oil in a small pot over medium heat; sauté the onion, carrot, and celery until the onions are translucent.
Add the minced garlic and dried thyme, stirring for 30 seconds until fragrant.
Pour in the chicken bone broth and bring the mixture to a gentle simmer.
Add the diced chicken to the pot and cook for 5 minutes.
In a small bowl, whisk together the whole wheat flour, baking powder, and a pinch of salt.
Stir the Greek yogurt into the flour mixture until a soft dough forms.
Drop small spoonfuls of the dough into the simmering broth, covering the pot with a lid.
Simmer for 10-12 minutes without lifting the lid to ensure the dumplings steam and become light and airy.
Serve hot in a bowl, ensuring a generous portion of chicken and dumplings in every bite.
