Dice the chicken breast into bite-sized pieces.
Heat the olive oil in a pot over medium heat and sauté the onions, carrots, and celery until they begin to soften.
Add the diced chicken to the pot and cook until the pieces are lightly browned on all sides.
Pour in the chicken bone broth and stir in the dried thyme, sea salt, and black pepper.
Bring the mixture to a gentle simmer over medium-low heat.
In a small mixing bowl, whisk together the almond flour, tapioca starch, and baking powder.
Stir the water into the flour mixture until a thick, cohesive dough forms.
Drop small spoonfuls of the dough into the simmering broth, spacing them apart.
Cover the pot with a tight-fitting lid and simmer for 10 to 12 minutes until the dumplings are firm and the chicken is fully cooked.
Garnish the dish with freshly chopped parsley and serve warm.
