Slice the chicken breast into 1-inch bite-sized pieces and season evenly with sea salt and black pepper.
In a small bowl, whisk together the orange juice, coconut aminos, minced fresh ginger, minced garlic, honey, and arrowroot powder until the starch is fully dissolved.
Heat the avocado oil in a large skillet over medium-high heat and add the chicken pieces, searing for 5-6 minutes until they are golden brown and cooked through.
While the chicken is browning, steam the broccoli florets in a steamer basket for 3-4 minutes until they reach a bright green, crisp-tender consistency.
Pour the orange glaze mixture into the skillet with the chicken and stir constantly for 1-2 minutes as the sauce bubbles and thickens into a glossy coating.
Add the steamed broccoli to the skillet, tossing gently to combine, and serve immediately topped with a sprinkle of sesame seeds.
