Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Trim the woody ends off the asparagus and toss the spears with one teaspoon of olive oil and a pinch of sea salt.
Spread the asparagus on the baking sheet and roast for 12-15 minutes until tender and slightly charred.
While the asparagus roasts, steam the cauliflower florets in a steamer basket over boiling water for 10-12 minutes until very soft.
Transfer the steamed cauliflower to a blender or food processor with the Greek yogurt and a pinch of salt, blending until completely smooth and creamy.
Heat the remaining teaspoon of olive oil in a non-stick skillet over medium-high heat.
Season the salmon fillet with salt and pepper, then place it in the hot skillet skin-side down.
Sear the salmon for 4-5 minutes until the skin is crisp, then flip and cook for another 3-4 minutes until the center is just opaque.
During the last minute of searing the salmon, add the minced garlic to the pan to lightly toast it without burning.
Spoon the cauliflower mash onto a plate, top with the seared salmon and garlic, and serve the roasted asparagus alongside.
