Steam the cauliflower florets until very tender, then blend with half of the sea salt and a splash of water until completely smooth and creamy.
Toss the asparagus spears with olive oil, remaining salt, and pepper, then roast at 400°F for 8-10 minutes until tender-crisp.
Pat the sea scallops extremely dry with paper towels to ensure a proper golden crust, then season lightly with pepper.
Heat a stainless steel or cast iron skillet over medium-high heat with the ghee until shimmering.
Place scallops in the pan, leaving space between them, and sear undisturbed for 2 minutes until a deep golden crust forms.
Flip the scallops, add the minced garlic to the pan, and cook for 1 more minute while basting the scallops with the melted ghee.
Remove the pan from heat, stir in the lemon juice and fresh parsley to create a light pan sauce.
Spoon the cauliflower mash onto a plate, top with the roasted asparagus and scallops, then drizzle the lemon-herb ghee over the top.
