Pat the chicken breast dry with a paper towel and cut into bite-sized cubes.
In a small bowl, toss the chicken cubes with arrowroot powder, sea salt, and black pepper until evenly coated.
In another small bowl, whisk together the honey, tamari, minced garlic, and grated fresh ginger to create the glaze.
Heat the olive oil in a large non-stick skillet over medium-high heat. Add the chicken and sear until golden brown and cooked through, about 6-8 minutes.
While the chicken cooks, steam the broccoli florets and sliced red bell pepper until they are tender-crisp and vibrant.
Reduce the skillet heat to medium and pour the honey-garlic sauce over the chicken. Simmer for 1-2 minutes until the sauce thickens into a glossy glaze that coats the chicken.
Place the cooked brown rice in a bowl, top with the glazed chicken and steamed vegetables, and drizzle any remaining sauce from the pan over the top.
