Cut the chicken breast into bite-sized pieces and season with sea salt and black pepper.
Place the chicken in a bowl and toss with arrowroot starch until each piece is lightly and evenly coated.
In a small bowl, whisk together the orange juice, orange zest, coconut aminos, honey, minced ginger, and minced garlic to create the sauce.
Heat avocado oil in a large skillet over medium-high heat. Add the chicken in a single layer and cook for 3-4 minutes per side until golden brown and crispy.
While the chicken cooks, steam the broccoli florets for 4-5 minutes until bright green and tender-crisp.
Once the chicken is crispy, pour the sauce into the skillet. Stir constantly for 1-2 minutes until the sauce thickens and glazes the chicken.
Add the steamed broccoli to the skillet and toss everything together to coat in the orange glaze.
Transfer to a plate and garnish with sesame seeds before serving.
