Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F (204°C). Place 4 salmon fillets (6 oz each) skin-side down on a baking sheet lined with parchment paper. Drizzle 1 tbsp olive oil over salmon and season with 1/2 tsp sea salt, 1/4 tsp black pepper, and 1/2 tsp garlic powder.
  2. Step 2: Arrange 1 lb trimmed asparagus spears on the same baking sheet around the salmon. Drizzle with 1 tbsp olive oil and season with 1/2 tsp sea salt and 1/4 tsp black pepper.
  3. Step 3: Roast salmon and asparagus in the oven for 12-15 minutes until salmon flakes easily with a fork and asparagus is tender-crisp.
  4. Step 4: While salmon roasts, combine 1 medium diced ripe avocado, 1 cup halved cherry tomatoes, 1/4 cup finely diced red onion, 2 tbsp chopped fresh cilantro, 2 tbsp fresh lime juice, and 1 tbsp olive oil in a bowl. Gently toss to combine and season with 1/4 tsp sea salt.
  5. Step 5: Remove salmon and asparagus from oven. Spoon avocado salsa over each salmon fillet and serve immediately with the roasted asparagus.
