In a small bowl, whisk together the orange juice, coconut aminos, raw honey, minced ginger, and minced garlic to create the glaze.
Pat the chicken breast dry and cut into 1-inch cubes. In a medium bowl, toss the chicken with arrowroot powder, sea salt, and black pepper until evenly coated.
Heat avocado oil in a large skillet or wok over medium-high heat. Add the chicken in a single layer and cook for 5-6 minutes, turning occasionally, until golden brown and cooked through.
Remove the chicken from the pan and set aside. Add the broccoli, sliced bell pepper, and snap peas to the same pan with a splash of water. Cover and steam for 2-3 minutes until tender-crisp.
Return the chicken to the pan and pour the orange glaze over the mixture. Toss constantly for 1-2 minutes until the sauce thickens and coats everything beautifully.
Remove from heat and drizzle with toasted sesame oil. Garnish with sesame seeds before serving.
