Preheat your oven to 400°F (200°C).
Trim the woody ends off the asparagus and place them on a baking sheet.
Toss the asparagus with 0.5 tsp of olive oil, half of the sea salt, and half of the black pepper.
Roast the asparagus for 10-12 minutes until tender-crisp and slightly charred.
While asparagus roasts, season the salmon fillet with the remaining salt, pepper, and dried oregano.
Heat the remaining 1 tsp of olive oil in a non-stick skillet over medium-high heat.
Place the salmon in the pan 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 it reaches your desired level of doneness.
In a small bowl, whisk together the fresh lemon juice and minced garlic.
Plate the salmon alongside the roasted asparagus and drizzle the lemon-garlic mixture over both before serving.
