Preheat your oven to 400°F (200°C) and line a small baking sheet with parchment paper.
Trim the woody ends off the asparagus and place the spears on the baking sheet, tossing them with the olive oil, sea salt, and black pepper.
In a small bowl, whisk together the tamari, maple syrup, freshly grated ginger, and minced garlic to create the clean teriyaki glaze.
Heat a high-quality non-stick or cast-iron skillet over medium-high heat and place the salmon fillet skin-side down, searing for 4-5 minutes until the skin is crispy.
Carefully flip the salmon and brush the top generously with half of the prepared teriyaki glaze.
Place the salmon on the baking sheet next to the asparagus and roast in the oven for 8-10 minutes until the salmon is flaky and the asparagus is tender.
Remove from the oven, brush with the remaining glaze, and sprinkle with sesame seeds before serving hot.
