In a small bowl, whisk together the coconut aminos, honey, rice vinegar, arrowroot powder, and red pepper flakes until the arrowroot is fully dissolved.
Place the broccoli florets in a steamer basket over boiling water and steam for 4 to 5 minutes until tender-crisp and vibrant green.
While the broccoli steams, heat the toasted sesame oil in a large skillet over medium-high heat.
Season the cubed chicken breast with sea salt and black pepper, then add it to the skillet.
Cook the chicken for 5 to 6 minutes, stirring occasionally, until golden brown and cooked through.
Add the minced ginger and garlic to the skillet with the chicken and sauté for 1 minute until fragrant.
Pour the prepared sauce into the skillet and stir constantly for 1 to 2 minutes until the glaze thickens and coats the chicken beautifully.
Serve the glazed chicken and steamed broccoli over the warm brown rice, garnished with sesame seeds and sliced green onions.
