Instructions

  1. Step 1: Preheat oven to 400°F (200°C). Pat salmon fillets dry with paper towels and place on a parchment-lined baking sheet.
  2. Step 2: Whisk 2 tbsp avocado oil, 1 tsp lemon zest, 1/4 tsp sea salt, and 1/8 tsp black pepper in a small bowl. Brush evenly over salmon.
  3. Step 3: Thinly slice 2 medium zucchini, 2 medium bell peppers, and 1 medium red onion into 1/4-inch rounds. Toss with 1 tbsp fresh dill and 1/8 tsp black pepper, then spread around salmon on the sheet pan.
  4. Step 4: Roast for 18-20 minutes until salmon is opaque and flakes easily with a fork, and vegetables are tender-crisp with golden edges.
