Preheat your oven to 400°F and line a baking sheet with parchment paper.
Trim the woody ends off the asparagus, toss with sesame oil, a pinch of sea salt, and black pepper, then roast for 12 minutes until tender-crisp.
Dice the chicken breast into one-inch cubes and toss in a bowl with arrowroot powder, sea salt, and black pepper until evenly coated.
Heat the avocado oil in a large non-stick skillet over medium-high heat and sear the chicken for 6 to 8 minutes until golden brown and crispy.
In a small bowl, whisk together the coconut aminos, honey, minced fresh ginger, and minced garlic.
Reduce the skillet heat to low, pour the sauce over the chicken, and toss continuously for 1 minute until the glaze is thick and glossy.
Arrange the roasted asparagus on a plate, top with the crispy teriyaki chicken, and garnish with sesame seeds.
