Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Trim the woody ends off the asparagus and place them on one side of the baking sheet, tossing with half of the olive oil and a pinch of the salt and pepper.
Pat the salmon fillet dry with a paper towel and place it on the other side of the baking sheet.
In a small bowl, whisk together the Dijon mustard, lemon juice, and the remaining olive oil.
Brush the mustard mixture evenly over the top of the salmon fillet.
In the same small bowl, combine the almond meal, dried parsley, garlic powder, and the remaining salt and pepper.
Press the almond herb mixture firmly onto the top of the salmon to create an even, golden crust.
Roast in the oven for 12-15 minutes until the salmon is flaky and the asparagus is tender and slightly charred.
