Preheat your oven to 400°F and line a baking sheet with parchment paper.
Toss the broccoli florets with half a tablespoon of olive oil, dried thyme, and a pinch of salt.
Spread the broccoli on the baking sheet and roast for 15-20 minutes until the edges are crisp.
While the broccoli roasts, steam the cauliflower florets until they are very tender, about 10 minutes.
Mash the steamed cauliflower with ghee, minced garlic, and salt until smooth and creamy.
Pat the salmon dry and season both sides with salt and black pepper.
Heat the remaining olive oil in a skillet over medium-high heat.
Place the salmon in the pan and sear for 4-5 minutes until the skin is golden and crispy.
Flip the salmon and cook for an additional 2-3 minutes until cooked through.
Plate the salmon over a bed of garlic cauliflower mash with the roasted broccoli on the side.
Finish the dish with a generous squeeze of fresh lemon juice.
