Preheat your oven to 400°F (200°C).
In a large skillet, melt the ghee over medium heat and sauté the diced onion, celery, and carrots until they begin to soften.
Add the diced chicken breast to the skillet and cook until the exterior is lightly browned.
In a small bowl, whisk the arrowroot powder into the chicken bone broth until smooth.
Pour the broth mixture and the coconut milk into the skillet, then stir in the frozen peas, garlic powder, thyme, sea salt, and black pepper.
Simmer the mixture for 5 minutes, stirring occasionally, until the sauce thickens into a creamy consistency.
Transfer the chicken and vegetable filling into an oven-safe baking dish or individual ramekin.
Sprinkle the almond flour evenly over the top of the filling.
Place in the oven and bake for 12-15 minutes until the almond flour topping is golden brown and the filling is bubbling.
