Prepare brown rice according to package directions and set aside.
In a small bowl, whisk together orange juice, coconut aminos, honey, minced ginger, minced garlic, and arrowroot powder to create the glaze.
Cut chicken breast into bite-sized pieces and season evenly with sea salt and black pepper.
Heat sesame oil in a large skillet or wok over medium-high heat until shimmering.
Add chicken to the skillet and cook until golden brown and cooked through, approximately 5-7 minutes.
Add broccoli florets and sliced red bell pepper to the skillet, sautéing for 3-4 minutes until they reach a tender-crisp texture.
Pour the orange glaze over the chicken and vegetables, stirring constantly until the sauce thickens and coats everything in a glossy finish.
Serve the stir-fry immediately over the fluffy brown rice and garnish with sesame seeds.
