Cut the chicken breast into bite-sized cubes and toss in a bowl with arrowroot powder, sea salt, and black pepper until evenly coated.
In a small jar or bowl, whisk together the honey, tamari, sesame oil, minced garlic, and grated ginger to create the glaze.
Heat the olive oil in a non-stick skillet over medium-high heat and add the chicken cubes in a single layer.
Sear the chicken for 5-6 minutes, turning occasionally, until the edges are golden brown and crispy and the meat is cooked through.
While the chicken cooks, steam the broccoli florets for 3-4 minutes until they reach a vibrant green color and tender-crisp texture.
Reduce the skillet heat to low and pour the honey-garlic sauce over the chicken, stirring constantly for 1 minute until the sauce thickens into a glossy glaze.
Assemble the bowl by placing the cooked brown rice at the base, topped with the glazed chicken and steamed broccoli.
