Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper for easy cleanup.
Trim the woody ends off the asparagus spears and toss them directly on the baking sheet with olive oil, sea salt, and black pepper.
Roast the asparagus for 12-15 minutes until they are tender-crisp and showing slight charred edges.
While the vegetables roast, prepare the glaze by whisking together the coconut aminos, honey, minced ginger, minced garlic, and arrowroot powder in a small bowl.
Slice the chicken breast into bite-sized cubes and season lightly with a pinch of sea salt.
Heat the sesame oil in a large non-stick skillet over medium-high heat until shimmering.
Add the chicken to the skillet and sear for 5-6 minutes, turning occasionally, until golden brown and cooked through.
Pour the prepared teriyaki glaze over the chicken and stir constantly for 1-2 minutes until the sauce bubbles and thickens into a glossy coating.
Plate the crispy glazed chicken over the roasted asparagus and garnish with a sprinkle of sesame seeds before serving.
