Cut the chicken breast into bite-sized pieces and season evenly with the sea salt and black pepper.
In a small bowl, whisk together the orange juice, coconut aminos, arrowroot powder, minced ginger, and minced garlic to create the glaze.
Heat the avocado oil in a large skillet over medium-high heat until shimmering.
Add the chicken pieces to the skillet and cook until golden brown and cooked through, approximately 5 to 7 minutes.
Remove the chicken from the pan and set aside; add the broccoli florets and sliced red bell pepper to the same pan with a splash of water.
Cover the pan and steam the vegetables for 3 minutes until they are crisp-tender and vibrant green.
Return the chicken to the pan and pour the orange glaze over the mixture.
Toss everything together for 1 minute until the sauce thickens and coats the chicken and vegetables, then garnish with fresh orange zest before serving.
