Cook the brown rice according to package instructions and set aside.
In a small bowl, whisk together coconut aminos, honey, grated ginger, minced garlic, arrowroot powder, and water to create the teriyaki sauce.
Cut the chicken breast into bite-sized cubes and season with sea salt and black pepper.
Heat the toasted sesame oil in a large skillet or wok over medium-high heat.
Add the chicken to the skillet and sauté for 5-6 minutes until golden brown and cooked through.
Add the broccoli florets to the pan with a splash of water, covering for 2 minutes to steam-cook until vibrant green and tender-crisp.
Pour the teriyaki sauce over the chicken and broccoli, stirring constantly for 1 minute until the sauce thickens and coats everything evenly.
Serve the stir-fry over the warm brown rice and garnish with sesame seeds.
