Salmon with Creamy Avocado Sauce over Roasted Harissa Cauliflower

1. Preheat oven to 425F. Slice the cauliflower and drizzle olive oil on both sides to cover. Season with salt. In a small bowl, mix 2 tbsp harissa paste and 2 tbsp olive oil. Coat all sides of the cauliflower liberally.
2. Bake for 35 minutes, carefully flipping after the first 20 minutes. Should be nicely golden with a slight char.
3. Combine creamy avocado sauce ingredients in a blender, blend until smooth and creamy, and set aside. If the sauce is too thick you can add a pinch of cream, water or extra lemon juice.
4. Season salmon filets with salt on both sides. Heat 2 tbsp of butter over medium-high heat in a stainless pan or skillet. Once hot, add salmon filets and sear for 3-4 minutes per side for medium rare and 4-5 minutes per side for medium, depending on thickness.
5. Transfer salmon filets to a plate over the cauliflower slice and top with creamy avocado sauce. Sprinkle with fresh basil and serve immediately with a lemon or lime wedge.
