Prepare the brown rice according to package instructions or use pre-cooked rice for efficiency.
Cut the chicken breast into bite-sized cubes and toss in a bowl with arrowroot powder, sea salt, and black pepper until evenly coated.
In a small glass jar, whisk together the honey, tamari, minced garlic, and grated ginger to create the glaze.
Heat sesame oil in a large skillet over medium-high heat and sear the chicken until golden brown and cooked through, about 6-8 minutes.
Steam the broccoli florets and sliced red bell peppers in a steamer basket until tender-crisp, approximately 4-5 minutes.
Pour the honey-garlic sauce into the skillet with the chicken, tossing constantly for 1-2 minutes until the sauce thickens into a glossy glaze.
Assemble the bowls by layering the cooked brown rice, steamed vegetables, and crispy chicken, then garnish with sesame seeds before serving.
