Heat olive oil in a small pot over medium heat and sauté the diced carrots, celery, and onion until softened.
Add the cubed chicken breast and cook until lightly browned on all sides.
Pour in the chicken bone broth, thyme, parsley, garlic powder, salt, and pepper, then bring to a gentle simmer.
In a small bowl, whisk together the almond flour, tapioca starch, and baking powder, then stir in one tablespoon of the warm broth to form a thick dough.
Drop small spoonfuls of the dough into the simmering broth, cover the pot, and cook for 5-7 minutes until the dumplings are firm and cooked through.
Remove from heat and stir in the Greek yogurt to create a creamy finish before serving.
