Pat the chicken breast dry with paper towels and cut into bite-sized cubes.
Place chicken in a bowl and toss with arrowroot powder, sea salt, and black pepper until evenly coated.
In a small jar, whisk together the honey, tamari, sesame oil, minced garlic, and grated ginger to create the sauce.
Heat avocado oil in a large skillet over medium-high heat and add the chicken in a single layer.
Cook the chicken for 6-8 minutes, turning occasionally, until the exterior is golden and crispy.
While chicken cooks, steam the broccoli florets for 4-5 minutes until tender-crisp and bright green.
Reduce the skillet heat to low and pour the honey-garlic sauce over the chicken, stirring for 1-2 minutes until the glaze is thick and glossy.
Assemble the bowls by placing the cooked brown rice at the bottom, topped with the glazed chicken and steamed broccoli.
