Instructions

  1. Step 1: Preheat oven to 425°F (220°C). Line a large sheet pan with parchment paper or foil.
  2. Step 2: In a small bowl, combine 4 tbsp olive oil and 2 tbsp Cajun seasoning. Reserve 1 tbsp of the mixture.

  5. Step 5: Roast for 12-15 minutes, or until salmon flakes easily with a fork and vegetables are tender.
  6. Step 6: Serve salmon and vegetables with 4 fresh lemon wedges squeezed over top for brightness.
