Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F. Place 4 salmon fillets on a lined baking sheet and brush each with 2 tablespoons olive oil. Sprinkle 1 teaspoon salt and 1/2 teaspoon black pepper evenly over the fillets. Roast for 12-15 minutes until salmon flakes easily with a fork.
  2. Step 2: While salmon roasts, combine 1 medium peeled and pitted ripe avocado, 2 tablespoons lime juice, 1 minced garlic clove, 2 tablespoons water, 2 tablespoons chopped fresh cilantro, and 1/2 small seeded chopped jalapeño (optional) in a blender or food processor. Blend until smooth and creamy.
  3. Step 3: Remove salmon from oven and let rest for 2 minutes. Serve each fillet topped with 2-3 tablespoons of the creamy avocado lime sauce.
