Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F and line a baking sheet with parchment paper. Place 4 salmon fillets skin-side down on the sheet. Drizzle with 1 tbsp olive oil and season with 1/2 tsp sea salt and 1/4 tsp black pepper.
  2. Step 2: Roast salmon in the oven for 12-15 minutes until it flakes easily with a fork but remains moist.
  3. Step 3: While salmon roasts, combine 1 medium diced avocado, 1 cup quartered cherry tomatoes, 2 tbsp finely diced red onion, 2 tbsp chopped fresh cilantro, 2 tbsp lime juice, 1 tbsp olive oil, 1/2 tsp sea salt, and 1/4 tsp black pepper in a bowl. Gently toss to combine.
  4. Step 4: Remove salmon from oven and plate. Spoon the avocado-tomato salsa generously over each fillet before serving.
