Cut the chicken breast into small, bite-sized cubes and finely dice the onion, carrots, and celery.
Heat the olive oil in a medium pot over medium heat; add the onion, carrots, and celery, sautéing until the vegetables are slightly softened.
Add the chicken cubes to the pot and cook for 2-3 minutes until the exterior is no longer pink.
Pour in the chicken bone broth, dried thyme, sea salt, and black pepper, then bring the mixture to a gentle simmer.
In a small bowl, whisk together the flour and baking powder, then stir in the water until a thick dough forms.
Drop small, marble-sized spoonfuls of the dough into the simmering broth, ensuring they are spaced apart.
Stir in the light coconut milk and frozen peas, then cover the pot with a lid.
Reduce the heat to low and let the stew simmer for 10 minutes until the dumplings are cooked through and the sauce has thickened.
Ladle the chicken and dumplings into a bowl and garnish with freshly chopped parsley before serving.
