Preheat your oven to 400°F.
Peel and cut the sweet potato into 1/2-inch thick rounds. Toss with a pinch of salt and a few drops of olive oil, then spread on a baking sheet.
Trim the asparagus by snapping off the woody ends. Place on the baking sheet with the sweet potato, drizzle with olive oil, and season with salt and pepper.
Roast the sweet potato and asparagus in the preheated oven for about 20 minutes, until tender and slightly caramelized.
While the vegetables roast, pat the salmon dry with a paper towel. Season both sides with salt, pepper, and a sprinkle of garlic powder if desired.
Heat a non-stick skillet over medium-high heat. Place the salmon skin-side down (if applicable) and sear for about 3-4 minutes until a golden crust forms.
Flip the salmon and cook for an additional 3-4 minutes, depending on thickness, until the interior is just opaque.
Plate the seared salmon with the roasted sweet potato rounds and asparagus. Optionally, finish with a squeeze of lemon juice for brightness.
Serve immediately and enjoy your balanced, nutrient-packed dinner.
