Heat the olive oil in a medium pot over medium heat and sauté the diced onion, carrots, and celery for 5 minutes until softened.
Add the cubed chicken breast to the pot and cook for 3-4 minutes until the exterior is no longer pink.
Stir in the chicken bone broth, sea salt, black pepper, and dried thyme, then bring the mixture to a gentle simmer.
In a small mixing bowl, whisk together the flour, baking powder, and chopped fresh parsley.
Slowly stir the almond milk into the flour mixture until a thick, tacky dough forms.
Using a small spoon, drop rounded tablespoons 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 12 minutes without lifting the lid to ensure the dumplings steam properly.
Ladle the chicken, vegetables, and dumplings into a bowl and serve immediately.
