Cut the chicken breast into bite-sized pieces and season them evenly with sea salt and black pepper.
In a small bowl, whisk together the coconut aminos, honey, minced garlic, and grated fresh ginger to create the teriyaki glaze.
Heat the sesame oil in a large skillet or wok over medium-high heat until it begins to shimmer.
Add the chicken to the skillet and sear for 5-6 minutes, stirring occasionally, until the pieces are golden brown and cooked through.
Toss in the broccoli florets along with a tablespoon of water, then cover the pan with a lid for 2 minutes to steam the broccoli until it is vibrant green and tender-crisp.
Remove the lid, pour the prepared teriyaki glaze over the chicken and broccoli, and stir-fry for 1 minute until the sauce becomes glossy and thick.
Serve the stir-fry over the warm brown rice and garnish with sesame seeds for a final touch of texture.
