Preheat your oven to 400°F (200°C) and line a large rimmed baking sheet with parchment paper for easy cleanup.
Prepare the asparagus by snapping off the woody ends and placing the spears on one side of the prepared baking sheet.
In a small glass bowl, whisk together the coconut aminos, honey, toasted sesame oil, grated fresh ginger, and minced garlic to create the teriyaki glaze.
Place the salmon fillet on the other side of the baking sheet, ensuring there is enough space between the fish and the vegetables.
Drizzle the avocado oil over the asparagus and sprinkle with sea salt and black pepper, tossing well to coat each spear evenly.
Brush half of the prepared teriyaki glaze generously over the top and sides of the salmon fillet, reserving the rest for serving.
Roast in the center of the oven for 12 to 15 minutes, or until the salmon flakes easily with a fork and the asparagus is tender.
Remove from the oven, drizzle the remaining glaze over the salmon, and garnish the entire dish with a sprinkle of sesame seeds before serving.
