Pat the chicken breast dry with a paper towel and cut into bite-sized 1-inch cubes.
In a medium bowl, toss the chicken cubes 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.
Place a steamer basket over boiling water and steam the broccoli florets and sliced bell peppers for 4-5 minutes until tender-crisp and bright.
Heat the sesame oil in a large non-stick skillet over medium-high heat. Add the chicken in a single layer, cooking for 3-4 minutes per side until golden brown and crispy.
Pour the honey-garlic glaze over the chicken in the skillet. Toss continuously for 1-2 minutes until the sauce thickens and becomes sticky, coating every piece of chicken.
Assemble the bowl by placing the fluffy cooked brown rice at the base, topped with the steamed vegetables and the crispy glazed chicken.
Garnish with sesame seeds and serve immediately while hot.
