In a small bowl, whisk together the coconut aminos, honey, grated ginger, minced garlic, and arrowroot powder to create the teriyaki sauce.
Slice the chicken breast into bite-sized pieces and season with sea salt and black pepper.
Heat the sesame oil in a large skillet or wok over medium-high heat.
Add the chicken to the pan and sauté for 5-6 minutes until golden brown and cooked through.
Remove the chicken from the pan and set aside, then add the broccoli, bell peppers, and snap peas to the same skillet.
Stir-fry the vegetables for 3-4 minutes until they are tender-crisp and vibrant.
Return the chicken to the pan and pour the teriyaki sauce over the mixture.
Toss everything together for 1-2 minutes until the sauce thickens into a glossy glaze that coats the chicken and vegetables.
Serve the stir-fry immediately over the warm, cooked brown rice.
