Dice the chicken breast into bite-sized pieces and finely chop the carrots, celery, and onion.
Heat the olive oil in a small pot over medium heat and sauté the carrots, celery, and onion until they begin to soften, about 5 minutes.
Add the minced garlic and diced chicken to the pot, cooking for 2-3 minutes until the chicken is browned on the outside.
Pour in the chicken bone broth, sea salt, black pepper, and dried thyme, then bring the mixture to a gentle simmer.
In a small bowl, whisk together the whole wheat flour and baking powder, then stir in the almond milk until a thick dough forms.
Drop small spoonfuls of the dough into the simmering broth, ensuring they are spaced apart.
Cover the pot with a tight-fitting lid and simmer on low for 10-12 minutes without lifting the lid, allowing the dumplings to steam and double in size.
Garnish with freshly chopped parsley and serve warm.
