Cut the chicken breast into bite-sized pieces and place them in a bowl.
Sprinkle the arrowroot starch, sea salt, and black pepper over the chicken, tossing until each piece is evenly coated.
Heat the avocado oil in a large skillet over medium-high heat until shimmering.
Add the chicken to the skillet in a single layer and cook for 5-7 minutes, turning occasionally, until golden and crispy.
While the chicken cooks, whisk together the honey, tamari, and minced garlic in a small bowl.
Pour the sauce over the crispy chicken and stir constantly for 1-2 minutes until the glaze is thick and glossy.
Steam the broccoli florets until tender-crisp and bright green.
Assemble the bowls by placing the cooked brown rice at the base, topping with the honey-garlic chicken and steamed broccoli.
Garnish with sesame seeds before serving.
