Preheat your oven to 400°F (200°C). Line a large rimmed baking sheet with parchment paper or aluminum foil for easy cleanup.
Place the trimmed asparagus and halved cherry tomatoes on one half of the baking sheet. Drizzle with olive oil, season with a pinch of salt and black pepper, and toss to coat evenly.
Place the salmon fillets on the other half of the baking sheet. Season the fillets evenly with the remaining salt and black pepper.
In a small mixing bowl, whisk together the melted butter, minced garlic, fresh parsley, fresh dill, and lemon juice until well combined.
Spoon or brush the garlic butter sauce generously over each salmon fillet, allowing some to pool around the edges.
Bake in the preheated oven for 12 to 15 minutes, or until the salmon is opaque and flakes easily with a fork, and the vegetables are tender.
Remove from the oven and serve immediately. Garnish with additional fresh herbs and lemon wedges if desired.
