In a small bowl, whisk together the orange juice, orange zest, coconut aminos, honey, minced ginger, and minced garlic to create the glaze.
Season the diced chicken breast evenly with the sea salt and black pepper.
Heat the avocado oil in a large skillet over medium-high heat and sear the chicken until it is golden brown and cooked through.
Add the broccoli florets and sliced red bell pepper to the skillet, sautéing for 4-5 minutes until the vegetables are tender-crisp.
Pour the prepared orange glaze over the chicken and vegetables, simmering for 2-3 minutes until the sauce thickens and coats the ingredients.
While the sauce simmers, steam the cauliflower rice in a separate pan or microwave until tender.
Serve the orange chicken and vegetables over the cauliflower rice, garnishing with sliced green onions and sesame seeds.
