In a small bowl, whisk together the fresh orange juice, coconut aminos, minced ginger, minced garlic, and arrowroot powder to create the glaze.
Heat the avocado oil in a large skillet or wok over medium-high heat.
Dice the chicken breast into bite-sized pieces and season with sea salt and black pepper.
Add the chicken to the skillet and sear until golden brown and cooked through, then remove and set aside.
Add the broccoli, sliced bell peppers, and snap peas to the same skillet, sautéing for 3-4 minutes until tender-crisp.
Return the chicken to the skillet and pour the orange glaze over the mixture.
Stir constantly for 1-2 minutes until the sauce thickens and coats the chicken and vegetables evenly.
In a separate small pan, lightly sauté the cauliflower rice for 3 minutes until tender.
Drizzle the stir-fry with toasted sesame oil and serve immediately over the cauliflower rice.
