Whisk orange juice, orange zest, coconut aminos, minced ginger, minced garlic, honey, and arrowroot powder in a small bowl until smooth.
Season the cubed chicken breast evenly with sea salt and black pepper.
Heat 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 5-7 minutes, then remove and set aside.
In the same pan, add the broccoli, sliced bell peppers, and snap peas, stir-frying for 3-4 minutes until they are tender-crisp.
Add the cauliflower rice to the pan and sauté for an additional 2 minutes to soften slightly.
Return the cooked chicken to the pan and pour the prepared orange glaze over the chicken and vegetables.
Toss everything constantly for 1-2 minutes until the sauce thickens and coats the ingredients in a glossy finish.
Garnish with sliced green onions and serve immediately while hot.
