Steam the cauliflower florets until very tender, about 10-12 minutes.
While cauliflower steams, season the salmon fillet with salt and pepper.
Heat half of the ghee in a non-stick skillet over medium-high heat.
Place salmon in the skillet skin-side down and sear for 4-5 minutes until the skin is crispy.
Flip the salmon and cook for another 3-4 minutes until cooked through, then remove from pan.
In the same skillet, add the remaining ghee, green beans, and minced garlic.
Sauté the green beans for 5-6 minutes until tender-crisp and slightly charred.
Drain the steamed cauliflower and mash or blend until smooth, seasoning with salt and pepper.
Plate the cauliflower mash, top with the salmon, and serve with the garlic green beans.
