Dice the chicken breast into bite-sized pieces and season evenly with sea salt and black pepper.
In a small bowl, whisk together the orange juice, orange zest, coconut aminos, arrowroot powder, and red pepper flakes to create the glaze.
Heat the toasted sesame oil in a large skillet or wok over medium-high heat.
Add the chicken to the skillet and cook until golden brown and cooked through, then remove the chicken and set it aside.
In the same skillet, add the minced garlic and grated fresh ginger, sautéing for 30 seconds until fragrant.
Add the broccoli florets, sliced red bell pepper, and snap peas to the pan, stir-frying for 3-4 minutes until tender-crisp.
Stir in the cauliflower rice and cook for an additional 2 minutes until heated through.
Return the cooked chicken to the skillet and pour the orange glaze over the chicken and vegetables.
Toss everything constantly for 1-2 minutes until the sauce thickens and coats the stir-fry beautifully.
