In a small bowl, whisk together the coconut aminos, toasted sesame oil, raw honey, grated fresh ginger, and minced garlic to create the teriyaki glaze.
Pat the chicken breast dry and cut into bite-sized cubes, then season evenly with sea salt and black pepper.
Heat the avocado oil in a large skillet or wok over medium-high heat until shimmering.
Add the chicken to the skillet and sear for 4-5 minutes until golden brown and cooked through, then remove the chicken and set aside.
Add the broccoli florets to the same skillet with a splash of water, covering with a lid for 2 minutes to steam until vibrant green and tender-crisp.
Return the chicken to the pan and pour the teriyaki glaze over the mixture, tossing constantly for 1 minute until the sauce thickens and coats everything beautifully.
Serve the stir-fry immediately over the warm brown rice and garnish with sesame seeds.
