Preheat your oven to 400°F and line a baking sheet with parchment paper for easy cleanup.
Toss the asparagus with half of the avocado oil, sea salt, and black pepper on the baking sheet; roast for 12 minutes until tender.
In a small bowl, whisk together the coconut aminos, honey, minced ginger, and minced garlic to create the teriyaki glaze.
Pat the salmon fillet completely dry with a paper towel and season both sides with the remaining salt and pepper.
Heat the remaining avocado oil in a cast-iron skillet over medium-high heat until shimmering.
Place the salmon skin-side down in the skillet and sear for 4 minutes without moving it until the skin is golden and crispy.
Carefully flip the salmon, pour the glaze into the pan, and cook for 2 more minutes while spooning the thickening sauce over the fish.
Plate the salmon over the roasted asparagus, drizzle with any remaining pan glaze, and garnish with sesame seeds.
