Dice the chicken breast into 1-inch cubes and toss in a bowl with arrowroot powder, sea salt, and black pepper until evenly coated.
In a small jar, whisk together the honey, tamari, minced garlic, and grated ginger to create the glaze.
Heat the sesame oil in a large non-stick skillet over medium-high heat.
Add the chicken to the skillet and sear for 5-6 minutes, turning occasionally, until the edges are golden and crispy.
While chicken cooks, steam the broccoli florets for 3-4 minutes until tender-crisp and bright green.
Pour the honey-garlic sauce over the chicken and simmer for 1-2 minutes until the sauce thickens and coats the chicken beautifully.
Assemble the bowls by layering the cooked brown rice, steamed broccoli, and crispy honey-garlic chicken.
Garnish with sesame seeds before serving.
