Pat the salmon fillet dry with a paper towel and season both sides with sea salt and black pepper.
Heat the avocado oil in a stainless steel or cast iron skillet over medium-high heat.
Place the salmon skin-side down in the hot pan and sear for 4-5 minutes until the skin is crispy.
Flip the salmon and cook for another 2-3 minutes until desired doneness is reached, then remove from the pan and set aside.
In a separate small skillet, melt the ghee over medium heat and add the minced garlic, sautéing until fragrant.
Add the fresh spinach to the skillet and toss until wilted, then pour in the heavy cream.
Simmer the spinach and cream for 1-2 minutes until the sauce thickens slightly.
Fluff the warm brown rice and place it on a plate.
Top the rice with the creamy spinach mixture and place the seared salmon on top.
Finish with a fresh squeeze of lemon juice over the fish before serving.
