Instructions

  1. Step 1: Preheat oven to 400°F. Line a baking sheet with parchment paper and place 4 salmon fillets skin-side down. Drizzle 1 tbsp olive oil over the fillets and season evenly with 1/2 tsp sea salt, 1/4 tsp black pepper, and 1/2 tsp garlic powder.
  2. Step 2: Roast the salmon in the oven for 12-15 minutes, until the fish flakes easily with a fork but remains moist.
  3. Step 3: While the salmon roasts, prepare the salsa by combining 1 large diced ripe avocado, 1 cup quartered cherry tomatoes, 1/4 cup finely diced red onion, and 1/4 cup chopped fresh cilantro in a bowl.
  4. Step 4: Add 2 tbsp fresh lime juice, 1 tbsp olive oil, 1/2 tsp sea salt, and 1/4 tsp black pepper to the salsa. Gently toss to combine, maintaining the avocado’s shape.
  5. Step 5: Once the salmon is cooked, remove from the oven and spoon generous amounts of the avocado and tomato salsa over each fillet before serving.
