Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Dice the chicken breast into one-inch bite-sized pieces and season them evenly with sea salt and black pepper.
In a small glass bowl, whisk together the orange juice, coconut aminos, honey, toasted sesame oil, grated ginger, minced garlic, and arrowroot powder until smooth.
Place the chicken pieces and sliced red bell peppers on the baking sheet, drizzle with half of the orange glaze, and toss to coat thoroughly.
Spread the chicken and peppers in a single layer and bake for 15 to 18 minutes until the chicken is cooked through and the glaze is bubbling.
While the chicken is in the oven, steam the broccoli florets in a steamer basket over boiling water for 4 to 5 minutes until tender-crisp and bright green.
Remove the chicken from the oven and drizzle with the remaining orange glaze to intensify the flavor.
Serve the glazed chicken and peppers over the warm brown rice with a side of steamed broccoli, then garnish with sesame seeds before enjoying the fresh citrusy aroma.
