Preheat the oven to 400°F (200°C). Line a rimmed baking sheet with parchment paper and arrange the salmon fillets skin-side down if they have skin.
In a small bowl, whisk together the melted butter, Dijon mustard, and honey until smooth; set aside.
In another bowl, combine the dry bread crumbs, very finely chopped pecans, and chopped fresh parsley.
Brush each salmon fillet lightly with the honey-Dijon butter mixture, then season with salt and pepper.
Evenly sprinkle the bread crumb and pecan mixture over the tops of the fillets, pressing lightly so it adheres.
Bake for 12 to 15 minutes, or until the thickest part of the salmon flakes easily with a fork; thicker fillets may need a few additional minutes.
Remove from the oven and serve garnished with lemon wedges.
