Pat the chicken breast dry with paper towels and dice into 1-inch bite-sized pieces.
Season the chicken pieces evenly with sea salt and black pepper.
In a small bowl, whisk together the coconut aminos, honey, grated fresh ginger, and minced garlic to create the teriyaki glaze.
Heat the toasted sesame oil in a large skillet over medium-high heat until shimmering.
Add the chicken to the skillet and sear until golden brown and cooked through, approximately 5 to 6 minutes.
Add the broccoli florets to the skillet with 2 tablespoons of water, then immediately cover with a lid to steam for 2 minutes until tender-crisp.
Remove the lid and pour the prepared teriyaki glaze over the chicken and broccoli.
Stir constantly for 1 to 2 minutes until the sauce thickens and creates a glossy coating.
Place the warm cooked brown rice in a serving bowl and top with the teriyaki chicken and broccoli.
Garnish with sesame seeds and serve immediately.
