Pat the chicken breast dry and cut into bite-sized cubes.
In a small bowl, toss the chicken cubes with arrowroot starch, sea salt, and black pepper until evenly coated.
Heat the sesame oil in a large skillet over medium-high heat.
Add the chicken to the skillet and sear for 5-7 minutes, turning occasionally, until golden brown and cooked through.
While chicken cooks, steam the broccoli florets until they reach a tender-crisp texture and bright green color.
In a small jar or bowl, whisk together the honey, tamari, minced garlic, and grated ginger.
Reduce the skillet heat to medium and pour the sauce over the chicken, stirring constantly for 1-2 minutes until the glaze is thick and glossy.
Divide the cooked brown rice and steamed broccoli into a bowl.
Top with the honey-garlic chicken and garnish with sesame seeds before serving.
