In a small bowl, whisk together the fresh orange juice, coconut aminos, minced ginger, garlic, and arrowroot powder to create the glaze.
Season the cubed chicken breast with sea salt and black pepper.
Heat avocado oil in a large skillet or wok over medium-high heat.
Add the chicken to the skillet and sauté until golden brown and cooked through, approximately 5-7 minutes.
Remove the chicken from the pan and set aside.
Add the broccoli, bell peppers, and snap peas to the same skillet, stir-frying for 3-4 minutes until tender-crisp.
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 and coats the ingredients thoroughly.
Serve the stir-fry over warm, cooked brown rice.
