Cut the chicken breast into 1-inch bite-sized pieces and season with the sea salt and black pepper.
In a small bowl, whisk together the coconut aminos, honey, minced ginger, minced garlic, and arrowroot powder to create the glaze.
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 5 to 7 minutes.
Add the broccoli florets to the skillet along with a splash of water, then cover with a lid for 2 minutes to steam until tender-crisp.
Remove the lid and pour the prepared teriyaki glaze over the chicken and broccoli.
Stir constantly for 1 minute until the sauce thickens and coats the ingredients thoroughly.
Garnish with sesame seeds and serve immediately.
