Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Cut the chicken breast into 1-inch bite-sized cubes and chop the bell pepper into similar sized pieces.
Place the chicken, broccoli florets, and bell peppers on the baking sheet. Drizzle with avocado oil and season with sea salt, black pepper, and garlic powder.
Toss everything well to ensure an even coating, then spread into a single layer to ensure the chicken gets crispy.
Roast in the oven for 18-20 minutes, or until the chicken is cooked through and the vegetables are tender-crisp with slightly charred edges.
While the chicken roasts, whisk together the coconut aminos, honey, and ground ginger in a small bowl to create the teriyaki glaze.
Remove the tray from the oven, pour the glaze over the chicken and vegetables, and toss directly on the pan to coat.
Serve the crispy chicken and vegetables over the warm cooked brown rice and garnish with sesame seeds.
