Preheat your oven to 425°F (220°C).
Peel and cube the sweet potato, and trim the ends of the asparagus. Toss both with olive oil, salt, pepper, and a light sprinkle of garlic powder.
Spread the sweet potato cubes on a baking sheet and roast for 20-25 minutes, stirring halfway through, until tender and slightly caramelized.
About 10 minutes before the sweet potatoes are done, place the asparagus on a separate baking sheet and roast for 10-12 minutes, until just tender.
Meanwhile, season the salmon fillet with salt, pepper, and a pinch of garlic powder. Heat a non-stick skillet over medium-high heat.
Sear the salmon, skin-side down first (if applicable), for about 3-4 minutes until a crust forms, then carefully flip and cook for an additional 3-4 minutes until the salmon is just cooked through.
Plate the seared salmon alongside the roasted sweet potatoes and asparagus. Serve immediately and enjoy your balanced dinner.
