Prepare the brown rice according to package instructions and set aside.
Dice the chicken breast into 1-inch cubes and toss in a bowl with the arrowroot powder, sea salt, and black pepper until evenly coated.
In a small bowl, whisk together the honey, tamari, minced garlic, and grated fresh ginger to create the glaze.
Heat the sesame oil in a large non-stick skillet over medium-high heat.
Add the chicken to the skillet and sear until golden brown and crispy on all sides, approximately 6-8 minutes.
Add the broccoli florets and sliced red bell pepper to the skillet, sautéing for 3-4 minutes until the vegetables are tender-crisp.
Pour the honey-garlic glaze over the chicken and vegetables, stirring constantly for 1-2 minutes until the sauce thickens and becomes glossy.
Serve the crispy chicken and vegetable mixture over the warm brown rice.
