Cut the chicken breast into bite-sized cubes and season evenly with sea salt and black pepper.
In a small mixing bowl, whisk together the coconut aminos, raw honey, minced ginger, and sesame oil to create the teriyaki glaze.
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.
Remove the chicken from the pan and set aside; add the broccoli florets to the same pan with a tablespoon of water.
Cover the pan for 2 to 3 minutes to steam the broccoli until it is bright green and tender-crisp.
Add the minced garlic to the pan and sauté for 30 seconds until fragrant, then return the chicken to the skillet.
Pour the prepared sauce over the chicken and broccoli, tossing constantly for 1 minute until the glaze thickens and coats everything.
Garnish with sliced green onions and sesame seeds before serving hot.
