Dice the chicken breast into bite-sized pieces and toss in a bowl with arrowroot powder, sea salt, and black pepper until evenly coated.
Heat the sesame oil in a large non-stick skillet over medium-high heat.
Add the chicken to the skillet and sear for 6-8 minutes, turning occasionally, until the edges are golden and crispy.
While the chicken cooks, steam the broccoli florets in a steamer basket for 4-5 minutes until tender-crisp and bright green.
In a small ramekin, whisk together the honey, tamari, minced garlic, and grated ginger.
Reduce the skillet heat to medium and pour the sauce over the chicken, tossing constantly for 1-2 minutes until the glaze is thick and glossy.
Build your bowl by layering the cooked brown rice, steamed broccoli, and the honey-garlic chicken.
Garnish with sesame seeds and serve immediately.
