Instructions

  1. Step 1: Preheat oven to 425°F. On a large rimmed baking sheet, toss 4 cups cauliflower florets and 2 cups halved baby carrots with 2 tbsp olive oil, 1 tsp sea salt, and 1/4 tsp black pepper. Spread evenly and roast for 15 minutes.
  2. Step 2: Meanwhile, in a small bowl, mix 2 tbsp harissa paste with 1 tbsp olive oil and 1 tsp lemon zest.
  3. Step 3: Remove the baking sheet from oven. Push the vegetables to the sides and place 4 salmon fillets (6 oz each) skin-side down in the center. Brush each fillet generously with the harissa mixture and sprinkle with 1/2 tsp sea salt and 1/4 tsp black pepper.
  4. Step 4: Return the sheet pan to the oven and roast for an additional 12-15 minutes until salmon is opaque and flakes easily with a fork and vegetables are tender.
  5. Step 5: Sprinkle 2 tbsp chopped fresh parsley over the salmon and vegetables before serving.
