In a small bowl, whisk together the coconut aminos, rice vinegar, honey, arrowroot powder, minced ginger, minced garlic, and red pepper flakes to create the sauce.
Dice the chicken breast into bite-sized pieces and season evenly with sea salt and black pepper.
Heat the avocado oil in a large skillet or wok over medium-high heat until shimmering.
Add the chicken to the skillet and sear for 5-6 minutes, stirring occasionally, until golden brown and cooked through.
Add the broccoli florets to the pan with a splash of water, then cover with a lid for 2 minutes to steam until tender-crisp.
Remove the lid and pour the sauce over the chicken and broccoli, tossing constantly for 1 minute until the glaze thickens and becomes glossy.
In a separate pan or microwave, lightly steam the cauliflower rice until heated through.
Plate the cauliflower rice and top with the General Tso's chicken and broccoli, garnishing with sliced green onions.
