Ingredients

Instructions

  1. Step 1: Preheat the oven to 400°F. Place 4 salmon fillets on a lined baking sheet. Drizzle 2 tbsp olive oil over the salmon and season evenly with 1/2 tsp sea salt, 1/4 tsp black pepper, 1/2 tsp garlic powder, and 1 tbsp chopped fresh dill. Roast for 12-15 minutes until salmon flakes easily with a fork.
  2. Step 2: Meanwhile, toss 1 lb trimmed asparagus with 1 tbsp olive oil, 1/4 tsp sea salt, and 1/4 tsp black pepper. Spread on a separate baking sheet and roast alongside the salmon for 12-15 minutes until tender-crisp.
  3. Step 3: While the fish and asparagus roast, pulse 1 medium cauliflower head (about 4 cups riced) in a food processor until it resembles rice grains. Heat 1 tbsp olive oil in a large skillet over medium heat.
  4. Step 4: Add the cauliflower rice to the skillet and cook, stirring frequently, for 5-7 minutes until softened but not mushy. Remove from heat and stir in juice and zest of 1 large lemon, 1 tbsp chopped fresh parsley, and a pinch of salt and pepper.
  5. Step 5: Plate the roasted salmon over a bed of lemon-cauliflower rice with asparagus spears on the side for a bright, Whole30-compliant meal.
