Dice the chicken breast into bite-sized pieces and season with sea salt and black pepper.
In a small bowl, whisk together the orange juice, coconut aminos, minced ginger, and arrowroot powder to create the glaze.
Heat the sesame oil in a large skillet or wok over medium-high heat.
Add the chicken to the skillet and sear until golden brown and cooked through, then remove and set aside.
Add the broccoli florets and diced red bell pepper to the same skillet, sautéing for 3-4 minutes until tender-crisp.
Stir in the minced garlic and cook for 30 seconds until fragrant.
Return the chicken to the skillet and pour the orange glaze over the mixture, stirring constantly until the sauce thickens and coats everything.
In a separate small pan, lightly sauté the cauliflower rice for 2-3 minutes until heated through.
Plate the stir-fry over the cauliflower rice and garnish with sesame seeds before serving.
