Cook the brown rice according to package instructions and set aside.
In a small bowl, whisk together the coconut aminos, honey, minced fresh ginger, and minced garlic to create the teriyaki sauce.
Heat the avocado oil in a large skillet or wok over medium-high heat.
Season the diced chicken breast with sea salt and black pepper, then add it to the skillet.
Sear the chicken until golden brown and cooked through, approximately 5-7 minutes.
Add the broccoli florets to the pan with a small splash of water, covering with a lid for 2 minutes to lightly steam.
Remove the lid, pour in the prepared teriyaki sauce and sesame oil, and toss everything together.
Continue to cook for 1-2 minutes until the sauce thickens into a glossy glaze that coats the chicken and vegetables.
Serve the stir-fry immediately over the bed of cooked brown rice.
