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 place them in a large mixing bowl.
Add the broccoli florets and diced red bell pepper to the bowl with the chicken pieces.
In a small glass jar or bowl, whisk together the fresh orange juice, coconut aminos, arrowroot powder, toasted sesame oil, grated ginger, and minced garlic until smooth.
Pour the orange glaze over the chicken and vegetables, then season with sea salt and black pepper, tossing well to ensure everything is thoroughly coated.
Spread the mixture in a single, even layer on the prepared baking sheet.
Bake for 18 to 20 minutes, or until the chicken is cooked through and the broccoli edges are slightly caramelized.
While the chicken bakes, prepare the jasmine rice according to package instructions.
Serve the baked orange chicken and vegetables over the fluffy jasmine rice.
Garnish with sesame seeds and freshly sliced green onions before serving.
