Dice the chicken breast into bite-sized pieces and season evenly with sea salt and black pepper.
In a small bowl, whisk together the coconut aminos, honey, rice vinegar, arrowroot powder, minced garlic, grated ginger, and red pepper flakes to create the sauce.
Heat the avocado oil in a large skillet or wok over medium-high heat until shimmering.
Add the chicken to the skillet and sear until golden brown and cooked through, approximately 5 to 7 minutes, then remove from the pan and set aside.
Add the broccoli florets and sliced bell peppers to the same skillet with a splash of water, covering for 2 minutes to steam until they are tender-crisp.
Return the chicken to the skillet and pour the prepared sauce over the mixture, stirring constantly for 1 to 2 minutes until the sauce thickens and coats everything.
In a separate small pan, lightly sauté the cauliflower rice for 3 to 4 minutes until tender and heated through.
Portion the cauliflower rice into a bowl and top with the hot General Tso's chicken and vegetable stir-fry.
