Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Toss the broccoli florets on the baking sheet with 0.5 tbsp of avocado oil, sea salt, and black pepper.
Roast the broccoli for 15-18 minutes until the edges are slightly charred and the stems are tender.
While the broccoli roasts, pat the chicken breast cubes dry with a paper towel and toss them in a bowl with the arrowroot powder until lightly coated.
Heat the remaining 0.5 tbsp of avocado oil in a large non-stick skillet over medium-high heat.
Add the chicken to the skillet and sear for 5-6 minutes, turning occasionally, until golden brown and cooked through.
In a small bowl, whisk together the coconut aminos, toasted sesame oil, honey, grated fresh ginger, and minced garlic.
Reduce the skillet heat to medium, pour the sauce mixture over the chicken, and stir constantly for 1-2 minutes until the glaze becomes thick and glossy.
Plate the crispy chicken alongside the roasted broccoli and garnish with sesame seeds before serving.
