In a small bowl, whisk together the orange juice, orange zest, coconut aminos, honey, grated ginger, minced garlic, and arrowroot powder until smooth.
Cut the chicken breast into bite-sized pieces and season evenly with sea salt and black pepper.
Heat the avocado 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 to 6 minutes.
Remove the chicken from the pan and set aside on a plate.
Add the broccoli, snap peas, and sliced bell peppers to the same skillet with a tablespoon of water; cover and steam for 3 minutes until tender-crisp.
Return the chicken to the pan and pour the prepared orange sauce over the chicken and vegetables.
Toss everything together for 1 to 2 minutes until the sauce bubbles and thickens into a glossy glaze.
Garnish with thinly sliced green onions and serve immediately.
