Preheat oven to 400°F and line a baking sheet with parchment paper.
Toss asparagus with toasted sesame oil, sea salt, and black pepper, then spread in a single layer on the baking sheet.
In a small bowl, whisk together tamari, honey, grated ginger, and minced garlic to create the teriyaki glaze.
Pat the salmon dry and season lightly with sea salt and black pepper.
Heat avocado oil in a cast-iron skillet over medium-high heat.
Place salmon skin-side up in the skillet and sear for 3 minutes until a golden crust forms.
Flip the salmon, pour the teriyaki glaze over the top, and transfer the skillet to the oven along with the asparagus tray.
Roast for 8-10 minutes until the salmon is flaky and the asparagus is tender.
Spoon any remaining glaze from the pan over the salmon before serving.
