Cut the chicken breast into bite-sized cubes and season evenly with sea salt and black pepper.
In a small mixing bowl, whisk together the fresh orange juice, tamari, honey, arrowroot powder, minced ginger, and minced garlic to create the glaze.
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 7 minutes, then remove from the pan and set aside.
In the same skillet, add the broccoli florets, snap peas, and sliced red bell pepper, sautéing for 3 to 4 minutes until they are tender-crisp.
Return the cooked chicken to the skillet and pour the orange glaze over the mixture, stirring constantly for 1 to 2 minutes until the sauce thickens and coats the ingredients.
In a separate small pan, lightly sauté the cauliflower rice with the toasted sesame oil for 2 to 3 minutes until warmed through.
Divide the cauliflower rice into bowls and top with the orange chicken stir-fry, finishing with a garnish of sesame seeds and sliced green onions.
