Pat the chicken breast dry and dice into bite-sized pieces, then season with sea salt and black pepper.
In a small bowl, whisk together the coconut aminos, honey, minced ginger, and minced garlic to create the teriyaki glaze.
Heat the sesame oil in a large skillet over medium-high heat and sear the chicken until golden brown and cooked through.
Remove the chicken from the pan and add the broccoli, carrots, and bell peppers, sautéing until tender-crisp.
Add the cauliflower rice to the skillet and cook for 2-3 minutes until heated through and slightly softened.
Return the chicken to the pan, pour the teriyaki sauce over the mixture, and toss until everything is coated in a glossy glaze.
Garnish with sesame seeds and serve immediately.
