In a small bowl, whisk together the fresh orange juice, coconut aminos, honey, minced ginger, minced garlic, and arrowroot powder until the mixture is smooth and well-combined.
Cut the chicken breast into bite-sized pieces and season them 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 seasoned chicken to the skillet and sauté for 5-6 minutes, stirring occasionally, until the pieces are golden brown and fully cooked through.
Remove the chicken from the skillet and set it aside on a plate.
In the same skillet, add the broccoli florets, sliced red bell pepper, and sugar snap peas, sautéing for 3-4 minutes until they reach a tender-crisp texture.
Return the cooked chicken to the skillet and pour the prepared orange sauce over the chicken and vegetables.
Toss everything together constantly for 1-2 minutes until the sauce thickens into a glossy glaze that coats the ingredients.
Remove from heat and garnish with sesame seeds and thinly sliced green onions before serving.
