Heat the extra virgin olive oil in a medium pot over medium heat and sauté the diced onion, carrots, and celery until the onions are translucent.
Add the chicken breast, bone broth, water, sea salt, black pepper, and dried thyme to the pot.
Bring the liquid to a gentle simmer, cover, and cook for 12-15 minutes or until the chicken is cooked through.
Remove the chicken breast from the pot, shred it using two forks, and set it aside.
In a small mixing bowl, whisk together the cassava flour, baking powder, and chopped fresh parsley.
Stir in the unsweetened almond milk to the flour mixture until a thick, tacky dough forms.
Drop the dough by the tablespoonful into the simmering broth, cover the pot tightly, and steam for 6-8 minutes without lifting the lid.
Gently stir the shredded chicken back into the pot and serve immediately while the dumplings are light and airy.
