Cut the chicken breast into bite-sized pieces and toss in a bowl with sea salt, black pepper, and arrowroot powder 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 5-7 minutes, turning occasionally, until the edges are golden and crispy.
While the chicken cooks, whisk together the honey, tamari, minced garlic, and grated ginger in a small bowl.
Steam the broccoli florets in a steamer basket or microwave with a splash of water until tender-crisp.
Lower the skillet heat to medium and pour the honey-garlic sauce over the chicken, stirring constantly for 1-2 minutes until the sauce thickens into a glossy glaze.
Assemble the bowl by placing the cooked rice at the bottom, topping it with the glazed chicken and steamed broccoli.
Garnish with sesame seeds and serve immediately.
