Cut the chicken breast into bite-sized pieces and season lightly with a pinch of sea salt.
In a small bowl, whisk together the coconut aminos, rice vinegar, raw honey, arrowroot powder, and red pepper flakes to create the sauce.
Heat the avocado oil in a large skillet over medium-high heat.
Add the chicken to the skillet and sear until golden brown and cooked through, then remove and set aside.
In the same skillet, add the broccoli, bell pepper, minced ginger, and garlic, sautéing for 3-4 minutes until the vegetables are tender-crisp.
Return the chicken to the pan and pour the sauce over the mixture, stirring constantly until the sauce thickens and coats everything in a glossy glaze.
In a separate pan or the microwave, steam the cauliflower rice until tender.
Serve the chicken and vegetable stir-fry over the cauliflower rice, drizzling with toasted sesame oil and garnishing with sesame seeds.
