Instructions

  1. Step 1: Preheat oven to 425°F. Pat salmon dry and season both sides with 1/4 tsp sea salt and 1/8 tsp black pepper.
  2. Step 2: In a small bowl, mix 2 tbsp Dijon mustard, 2 tbsp chopped dill, and 1 tbsp chopped chives. Spread evenly over salmon fillets.
  3. Step 3: Heat 1 tbsp avocado oil in an oven-safe skillet over medium-high heat. Sear salmon skin-side down for 3 minutes until golden. Flip and cook for 2 more minutes.
  4. Step 4: Add 2 cups broccoli florets to the skillet, sprinkle with 1/4 tsp garlic powder, and roast for 12-15 minutes until broccoli is tender-crisp and salmon reaches 125°F internally.
