Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
In a small mixing bowl, combine the Greek yogurt, minced garlic, lemon zest, lemon juice, chopped dill, and chopped parsley until smooth.
Place the salmon fillet on one side of the prepared baking sheet and season the top with half of the sea salt and black pepper.
Spread the Greek yogurt mixture generously over the top of the salmon fillet, creating an even layer.
Trim the woody ends off the asparagus and place them on the other side of the baking sheet.
Drizzle the asparagus with olive oil and sprinkle with the remaining sea salt and black pepper, tossing to coat.
Bake for 12 to 15 minutes, or until the salmon is opaque and flakes easily with a fork and the asparagus is tender-crisp.
Serve immediately, garnishing with extra fresh herbs if desired.
