Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F. Line a baking sheet with parchment paper. Arrange 4 salmon fillets skin side down. Drizzle 1 tbsp olive oil, 2 minced garlic cloves, zest and juice of 1 lemon evenly over the salmon. Season with 1/2 tsp sea salt and 1/4 tsp black pepper.
  2. Step 2: On the same baking sheet, toss 1 lb trimmed asparagus with 1 tbsp olive oil, 1/4 tsp sea salt, and 1/4 tsp black pepper. Spread asparagus in a single layer beside the salmon.
  3. Step 3: Roast salmon and asparagus for 12-15 minutes until salmon is opaque and flakes easily with a fork, and asparagus is tender-crisp.
  4. Step 4: While roasting, heat 1 tbsp olive oil in a large skillet over medium heat. Add remaining 2 minced garlic cloves and sauté for 30 seconds until fragrant. Add 4 cups riced cauliflower and 1/4 tsp sea salt. Cook, stirring frequently, for 5-7 minutes until cauliflower is tender but not mushy.
  5. Step 5: Remove skillet from heat and stir in 2 tbsp chopped fresh parsley.
  6. Step 6: Serve each salmon fillet with roasted asparagus and a scoop of cauliflower rice.
