Preheat your oven to 400°F and line a large rimmed baking sheet with parchment paper for easy cleanup.
Trim the woody ends off the asparagus spears and place them on one side of the baking sheet.
Drizzle the asparagus with olive oil and sprinkle with half of the sea salt and black pepper, tossing to coat evenly.
In a small mixing bowl, stir together the Dijon mustard, lemon juice, dried parsley, and dried dill until well combined.
Place the salmon fillet on the other side of the baking sheet and spread the mustard-herb mixture over the top of the fish.
Sprinkle the almond meal over the mustard layer, followed by the remaining sea salt and black pepper, pressing down slightly so it sticks.
Slide the baking sheet into the oven and roast for 12 to 15 minutes, or until the salmon is opaque and flakes easily with a fork.
