In a small bowl, whisk together the fresh orange juice, coconut aminos, minced ginger, minced garlic, and arrowroot powder to create the glaze.
Cut the chicken breast into bite-sized pieces and season with sea salt and black pepper.
Heat the sesame oil in a large skillet or wok over medium-high heat.
Add the chicken to the skillet and cook until golden brown and cooked through, approximately 5 to 7 minutes.
Remove the chicken from the skillet and set aside on a plate.
Add the broccoli florets and sliced red bell pepper to the same skillet with a tablespoon of water; cover and steam for 2 minutes until vibrant and crisp-tender.
Return the chicken to the pan and pour the orange glaze over the chicken and vegetables.
Stir-fry constantly for 1 to 2 minutes until the sauce thickens and becomes glossy.
In a separate small pan, lightly sauté the cauliflower rice for 3 to 4 minutes until tender and heated through.
Serve the orange chicken mixture over the cauliflower rice and garnish with sliced green onions and sesame seeds.
