In a medium bowl, toss the cubed chicken breast with arrowroot powder, sea salt, and black pepper until evenly coated.
In a small jar, whisk together the coconut aminos, rice vinegar, raw honey, and water to create the stir-fry sauce.
Heat the toasted sesame oil in a large skillet or wok over medium-high heat.
Add the chicken to the skillet and sear until golden brown and crispy on all sides, about 5-6 minutes.
Stir in the sliced red bell pepper, snap peas, minced ginger, and garlic, sautéing for 3 minutes until the vegetables are tender-crisp.
Pour the sauce over the chicken and vegetables, stirring constantly as it bubbles and thickens into a glossy glaze.
Serve the stir-fry immediately over the warm cooked brown rice.
