Pat the salmon fillet dry with a paper towel and season both sides evenly with sea salt, black pepper, and garlic powder.
Heat the avocado oil in a medium non-stick skillet over medium-high heat until the oil is shimmering.
Place the salmon in the skillet skin-side down and sear for 4-5 minutes until the skin is golden and crispy.
Carefully flip the salmon and cook for an additional 2-3 minutes until the fish is opaque and flakes easily with a fork.
While the salmon is searing, steam the asparagus spears and cauliflower rice in a steamer basket or microwave until tender.
In a small bowl, whisk together the Greek yogurt, lemon juice, and finely chopped fresh dill until smooth.
Arrange the cauliflower rice and asparagus on a plate, top with the pan-seared salmon, and drizzle the lemon-dill sauce over the top.
