Steam the cauliflower florets until very tender, about 10-12 minutes.
Drain the cauliflower well and blend with ghee, salt, and pepper until it reaches a velvety, mash-like consistency.
Pat the salmon fillet dry with a paper towel and season both sides with sea salt and black pepper.
Heat avocado oil in a non-stick skillet over medium-high heat.
Place salmon in the pan skin-side down and sear for 4-5 minutes until the skin is crispy, then flip and cook for another 3 minutes.
Remove salmon from the pan and let it rest.
In the same skillet, add the green beans and a splash of water, covering for 2 minutes to steam-saute.
Remove the lid, add the minced garlic, and sauté for another 2 minutes until the beans are tender-crisp and fragrant.
Plate the cauliflower mash, top with the seared salmon, and serve the garlic green beans on the side.
