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 jar, whisk together the raw honey, tamari, minced garlic, and grated ginger to create the glaze.
Heat the toasted sesame oil in a large non-stick skillet over medium-high heat.
Add the chicken to the skillet and cook for 5-6 minutes, turning occasionally until the edges are golden and crispy.
Add the broccoli florets and sliced red bell pepper to the pan with a splash of water, covering for 2 minutes to lightly steam the vegetables.
Remove the lid and pour the honey-garlic glaze over the chicken and vegetables, stirring constantly for 1-2 minutes until the sauce thickens and coats everything.
Place the cooked brown rice in a bowl and top with the honey-garlic chicken and vegetable mixture.
Garnish with sliced green onions and serve immediately.
