In a small bowl, whisk together the orange juice, orange zest, coconut aminos, honey, ginger, garlic, and arrowroot powder to create the glaze.
Season the diced chicken breast with the sea salt and black pepper.
Heat the sesame oil in a large skillet or wok over medium-high heat.
Add the chicken to the skillet and cook until golden brown and cooked through, approximately 5 to 7 minutes.
Remove the chicken from the pan and set aside, then add the broccoli, bell peppers, and snap peas to the same skillet.
Stir-fry the vegetables for 3 to 4 minutes until they are tender-crisp.
Return the chicken to the pan and pour the orange glaze over the mixture.
Toss everything together for 1 to 2 minutes until the sauce thickens and coats the ingredients evenly.
Serve the stir-fry immediately over the warm cooked brown rice.
