Preheat your oven to 400°F and line a rimmed baking sheet with parchment paper.
Trim the woody ends off the asparagus and toss the spears on the baking sheet with 0.5 tbsp of avocado oil, a pinch of sea salt, and black pepper.
Roast the asparagus for 12-15 minutes until tender and slightly charred at the tips.
While the vegetables roast, whisk together the coconut aminos, honey, minced fresh ginger, and minced garlic in a small bowl to create the teriyaki base.
Season the chicken breast with the remaining sea salt and pepper. Heat the remaining 0.5 tbsp of avocado oil in a medium skillet over medium-high heat.
Sear the chicken for 6-7 minutes per side until the internal temperature reaches 165°F and the exterior is golden brown.
Reduce the skillet heat to low and pour in the teriyaki sauce. Simmer for 1-2 minutes, spooning the liquid over the chicken until it reduces into a thick, glossy glaze.
Slice the chicken into strips and serve immediately over the roasted asparagus, garnishing with sesame seeds and thinly sliced green onions.
