In a small bowl, whisk together the fresh orange juice, coconut aminos, arrowroot powder, minced ginger, and minced garlic to create the glaze.
Season the cubed chicken breast evenly with the sea salt and black pepper.
Heat the avocado oil in a large skillet or wok over medium-high heat until shimmering.
Add the chicken to the skillet and cook until golden brown and cooked through, approximately 5 to 7 minutes.
Add the broccoli florets and snap peas to the skillet, stir-frying for 3 to 4 minutes until the vegetables are tender-crisp and bright green.
Pour the orange glaze over the chicken and vegetables, tossing constantly for 1 minute until the sauce thickens and coats everything beautifully.
While the sauce thickens, steam or sauté the cauliflower rice in a separate pan until heated through and tender.
Serve the orange chicken and vegetables immediately over the cauliflower rice, garnished with sesame seeds and thinly sliced green onions.
