Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
In a small glass bowl, whisk together the tamari, honey, grated fresh ginger, and minced garlic to create a clean teriyaki glaze.
Toss the asparagus spears on one side of the baking sheet with half of the sesame oil, sea salt, and black pepper.
Heat the remaining sesame oil in a cast-iron or non-stick skillet over medium-high heat.
Season the salmon fillet with a pinch of salt and pepper, then sear for 2-3 minutes per side until a golden crust forms.
Transfer the seared salmon to the baking sheet and brush the top generously with the prepared tamari glaze.
Roast everything for 8-10 minutes until the salmon is cooked through and the asparagus is tender yet snappy.
Serve the glazed salmon over a bed of warm brown rice, drizzling any remaining glaze from the pan over the fish.
Finish the dish with a sprinkle of toasted sesame seeds for a nutty crunch.
