Preheat your oven to 425°F for the asparagus and sweet potato mash.
Peel and dice the sweet potato into cubes. Toss the cubes with a drizzle of olive oil, salt, pepper, and garlic powder. Spread evenly on a baking sheet.
Roast the sweet potato in the oven for about 20-25 minutes, or until tender.
Meanwhile, trim the tough ends from the asparagus. Toss them lightly with olive oil, salt, and pepper. Place the asparagus on another baking sheet and roast in the oven for about 10-12 minutes until tender.
Season the salmon fillet with salt and pepper. Heat a non-stick skillet over medium-high heat and sear the salmon skin-side down for about 3-4 minutes, then flip and cook for an additional 2-3 minutes, or until the salmon is cooked to your liking.
Once the sweet potatoes are roasted, transfer them to a bowl and mash until smooth. Adjust the seasoning if necessary.
Plate the seared salmon alongside a generous scoop of sweet potato mash and a serving of roasted asparagus.
Serve immediately and enjoy your nutritious, balanced dinner!
