Instructions

  1. Step 1: Preheat oven to 425°F. Toss 4 cups cauliflower florets with 2 tbsp olive oil, 1 tsp sea salt, and 1/4 tsp black pepper on a baking sheet. Roast for 25 minutes, stirring halfway through, until golden and tender.
  2. Step 2: Meanwhile, in a blender, combine 1 medium ripe avocado, 1/2 cup chopped fresh cilantro, 2 tbsp fresh lime juice, 1 minced garlic clove, 1/4 tsp sea salt, and 1 tbsp olive oil. Blend until smooth and creamy. Set aside.
  3. Step 3: Heat remaining 1 tbsp olive oil in a large skillet over medium-high heat. Season 4 salmon fillets (6 oz each) with 1/2 tsp sea salt and 1/4 tsp black pepper. Place skin side down and cook for 5-6 minutes until crispy, then flip and cook 2-3 minutes until just cooked through.
  4. Step 4: Serve salmon topped with 2 tbsp avocado-cilantro sauce per fillet alongside roasted cauliflower.
