Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Snap the woody ends off the asparagus and spread the spears on the baking sheet, tossing with half of the avocado oil, sea salt, and black pepper.
In a small glass bowl, whisk together the tamari, honey, grated fresh ginger, and minced garlic until the glaze is well combined.
Heat the remaining avocado oil in a cast-iron or oven-safe skillet over medium-high heat.
Season the salmon with a tiny pinch of salt and sear it skin-side up for 3-4 minutes until a golden-brown crust forms.
Carefully flip the salmon fillet, pour the prepared teriyaki glaze over the top, and place the skillet into the oven.
Roast the salmon and the asparagus simultaneously for 8-10 minutes until the fish flakes easily and the asparagus tips are lightly charred.
Remove from the oven, drizzle any remaining glaze from the pan over the salmon, and garnish with sesame seeds before serving.
