Instructions

  1. Step 1: Preheat oven to 425°F. Toss 4 cups cauliflower florets with 2 tbsp extra virgin olive oil, 1 tsp garlic powder, 1/2 tsp sea salt, and 1/2 tsp black pepper on a baking sheet. Roast for 25 minutes until golden and tender, stirring halfway through.
  2. Step 2: While cauliflower roasts, mix 1 large diced avocado, 1 cup halved cherry tomatoes, 1/4 cup finely chopped red onion, 2 tbsp chopped fresh cilantro, and 2 tbsp lime juice in a bowl. Season with a pinch of salt and set aside to meld.
  3. Step 3: Pat dry 4 salmon fillets (6 oz each) and season both sides with 1/2 tsp sea salt, 1/2 tsp black pepper, and 1 tsp smoked paprika. Heat 2 tbsp extra virgin olive oil in a large skillet over medium-high heat.
  4. Step 4: Place salmon skin-side down in the hot skillet and cook for 4-5 minutes until skin is crisp and golden. Flip and cook for an additional 3-4 minutes until salmon is opaque and flakes easily.
  5. Step 5: Serve each salmon fillet topped with 1/4 of the avocado salsa alongside a generous helping of roasted cauliflower.
