Pat the chicken breast dry with paper towels and season evenly with sea salt and black pepper.
In a small bowl, whisk together the orange juice, coconut aminos, grated ginger root, minced garlic, and arrowroot powder until smooth.
Heat the avocado oil in a large skillet or wok over medium-high heat until shimmering.
Add the chicken to the skillet and sear until golden brown and cooked through, approximately 5-6 minutes, then remove and set aside.
Add the broccoli florets, sliced red bell pepper, and sugar snap peas to the same skillet, sautéing for 3-4 minutes until tender-crisp.
Return the chicken to the pan and pour the orange sauce over the mixture, stirring constantly until the glaze thickens and coats all ingredients.
Serve the stir-fry immediately over a bed of steamed cauliflower rice.
