In a small bowl, whisk together coconut aminos, honey, grated ginger, minced garlic, and arrowroot powder to create the teriyaki glaze.
Dice 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 skillet and sear until golden brown and cooked through, approximately 6 to 8 minutes.
Remove the chicken from the pan and set aside; add the broccoli florets and sliced bell peppers to the same pan with a splash of water.
Cover and steam the vegetables for 3 to 4 minutes until they are tender-crisp and bright green.
Return the chicken to the pan and pour the prepared teriyaki glaze over the mixture.
Toss everything together for 1 to 2 minutes until the sauce thickens and coats the ingredients beautifully.
Serve the stir-fry over the warm, cooked brown rice and garnish with a sprinkle of sesame seeds.
