Preheat your oven to 400°F.
Snap the woody ends off the asparagus and place them on a baking sheet, seasoning with sea salt and black pepper.
Roast the asparagus for 12 to 15 minutes until tender-crisp.
Steam the cauliflower florets until very soft, then transfer them to a blender or food processor.
Add the ghee, minced garlic, and a pinch of salt to the cauliflower and blend until completely smooth.
Season the salmon fillet with sea salt and black pepper.
Heat avocado oil in a cast-iron skillet over medium-high heat.
Place the salmon skin-side down in the pan and sear for 4 minutes until the skin is golden and crisp.
Flip the salmon and cook for another 2 to 3 minutes until your desired doneness is reached.
Plate the cauliflower mash, top with the seared salmon, and serve with the roasted asparagus on the side.
