Preheat your oven to 425 degrees f. and line a large baking sheet with parchment paper.
In a small bowl, whisk together all the marinade ingredients.
Lay your salmon fillets onto your prepared baking sheet, skin-side-down. Add the asparagus and sweet pepper as shown.
Drizzle your marinade equally over the fish and vegetables and gently toss to coat.
Roast in your preheated oven for 12-15 minutes, or just until flaky.
Garnish with lemon wedges, sprinkle with freshly chopped parsley and enjoy!
