Pat the chicken breast dry and cut into 1-inch bite-sized cubes.
In a medium bowl, toss the chicken cubes with arrowroot powder, sea salt, and black pepper until evenly coated.
In a small jar or bowl, whisk together the honey, coconut aminos, rice vinegar, minced garlic, and grated fresh ginger.
Heat the sesame oil in a large non-stick skillet over medium-high heat until shimmering.
Add the chicken to the skillet in a single layer and cook for 6-8 minutes, turning occasionally, until golden and crispy on all sides.
While the chicken is cooking, steam the broccoli florets and sliced red bell pepper until they are tender-crisp and bright.
Pour the honey-garlic sauce over the chicken in the skillet and stir constantly for 1-2 minutes until the glaze is thick and glossy.
Place the warm brown rice in a bowl and top with the glazed chicken and the steamed vegetables.
