Preheat oven to 400°F and line a baking sheet with parchment paper.
Pat chicken wings dry with paper towels and toss with arrowroot powder, sea salt, and black pepper in a large bowl.
Spread wings on the prepared sheet and bake for 35-40 minutes, flipping halfway, until the skin is golden and crispy.
While wings bake, whisk honey, tamari, sesame oil, minced garlic, and grated ginger in a small saucepan over medium heat until the sauce simmers and thickens.
Steam the broccoli florets in a steamer basket for 4-5 minutes until bright green and tender.
Transfer the crispy wings to a bowl, pour the warm honey-garlic glaze over them, and toss to coat every piece.
Serve the wings immediately with the steamed broccoli and a sprinkle of sesame seeds.
