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 and toss the spears on the baking sheet with 1 tsp of avocado oil, sea salt, and black pepper.
Roast the asparagus for 12-15 minutes until they are tender and slightly charred at the tips.
While the asparagus roasts, whisk together the tamari, honey, sesame oil, minced ginger, and minced garlic in a small bowl to create the glaze.
Pat the salmon fillet completely dry with a paper towel and season the flesh side with a tiny pinch of sea salt.
Heat the remaining 1 tsp of avocado oil in a medium non-stick skillet over medium-high heat.
Place the salmon in the skillet skin-side up and sear for 4 minutes without moving it to develop a golden-brown crust.
Flip the salmon carefully, pour the teriyaki glaze into the pan, and simmer for 3 minutes while constantly spooning the thickening sauce over the fish.
Plate the salmon alongside the roasted asparagus, drizzle with any remaining glaze from the pan, and garnish with sesame seeds and sliced green onions.
