Pat the chicken breast dry and cut into bite-sized cubes.
In a small bowl, toss the chicken with arrowroot powder, sea salt, and black pepper until evenly coated.
Heat avocado oil in a large skillet over medium-high heat and sear the chicken until golden brown and cooked through.
While chicken cooks, steam the broccoli florets and sliced red bell pepper until tender-crisp.
In a small jar, whisk together the honey, tamari, minced garlic, grated ginger, and sesame oil.
Reduce the skillet heat to low, pour the sauce over the chicken, and stir for 1-2 minutes until the glaze thickens and coats the meat.
Serve the honey-garlic chicken over the cooked brown rice alongside the steamed vegetables.
