Cut the chicken breast into bite-sized cubes and toss in a bowl with arrowroot powder, sea salt, and black pepper until evenly coated.
Steam the broccoli florets until tender-crisp and set aside.
Heat the toasted sesame oil in a large skillet over medium-high heat.
Add the chicken to the skillet and cook for 5-7 minutes, turning occasionally until the exterior is golden and crispy.
In a small jar, whisk together the honey, tamari, minced garlic, and grated ginger to create the glaze.
Pour the sauce over the crispy chicken and simmer for 1-2 minutes until the glaze thickens and becomes sticky.
Assemble the bowls by layering the cooked brown rice, steamed broccoli, and the honey-garlic chicken.
Garnish with sesame seeds and sliced green onions before serving.
