Cut the chicken breast into 1-inch bite-sized pieces.
Heat the avocado oil in a large skillet or wok over medium-high heat.
Add the chicken to the pan and sear until golden brown and cooked through, approximately 6-8 minutes.
Remove the chicken from the pan and set it aside on a plate.
In the same pan, add the broccoli florets with a small splash of water, then cover and steam for 3 minutes until tender-crisp.
In a small bowl, whisk together the coconut aminos, rice vinegar, raw honey, minced garlic, grated ginger, and red pepper flakes.
Return the chicken to the pan and pour the sauce mixture over the chicken and broccoli.
Toss everything together for 1-2 minutes until the sauce thickens slightly and coats the ingredients evenly.
Drizzle with toasted sesame oil and garnish with sesame seeds and sliced green onions before serving.
