Pat the chicken breast dry with a paper towel and cut into bite-sized pieces.
In a small bowl, whisk together the honey, tamari, minced garlic, and grated ginger to create the glaze.
Place the chicken in a bowl and toss with arrowroot powder, sea salt, and black pepper until evenly coated.
Heat the avocado oil in a large skillet over medium-high heat and sear the chicken until golden brown and cooked through.
Steam the broccoli florets and sliced red bell pepper until tender-crisp, about 4-5 minutes.
Pour the honey-garlic glaze into the skillet with the chicken, stirring for 1-2 minutes until the sauce thickens and coats the meat.
Assemble the bowls by layering the cooked brown rice, steamed vegetables, and honey-garlic chicken, then garnish with sesame seeds.
