Cut the chicken breast into 1-inch cubes and season with the sea salt and black pepper.
In a small bowl, whisk together the fresh orange juice, coconut aminos, arrowroot powder, minced ginger, and minced garlic to create the glaze.
Heat the avocado oil in a large skillet or wok over medium-high heat.
Add the chicken to the skillet and sear for 5-6 minutes until golden brown and cooked through, then remove and set aside.
In the same skillet, add the sliced red bell pepper and sugar snap peas, sautéing for 3-4 minutes until tender-crisp.
Stir in the cauliflower rice and cook for an additional 2 minutes until heated through.
Return the chicken to the skillet and pour the orange glaze over the mixture.
Toss everything together for 1-2 minutes until the sauce thickens into a glossy coating.
Serve immediately garnished with sesame seeds and sliced green onions.
