In a small bowl, whisk together the fresh orange juice, coconut aminos, arrowroot powder, minced ginger, and minced garlic to create the glaze.
Cut the chicken breast into bite-sized pieces and season evenly with sea salt and black pepper.
Heat the sesame oil in a large skillet or wok over medium-high heat until shimmering.
Add the chicken to the skillet and sauté until golden brown and cooked through, approximately 5-6 minutes.
Remove the chicken from the pan and set aside, then add the snap peas and sliced red bell pepper to the same skillet.
Stir-fry the vegetables for 3 minutes until they are tender-crisp and vibrant.
Pour the orange sauce mixture into the skillet with the vegetables and simmer for 1-2 minutes until the sauce thickens into a glossy glaze.
Return the chicken to the skillet and toss everything together to coat thoroughly in the sauce.
Steam the cauliflower rice until tender and serve the orange chicken over the top, garnished with sesame seeds and sliced green onions.
