Preheat your oven to 425°F.
Peel and cut the sweet potato into 1/2-inch cubes, then toss with half the olive oil, salt, and pepper.
Spread the sweet potato cubes on a baking sheet and roast in the oven for 20-25 minutes until tender and lightly browned.
While the sweet potatoes roast, trim the asparagus and toss with the remaining olive oil, salt, and pepper; set aside.
Season the salmon fillet with salt and pepper on both sides.
Heat a non-stick skillet over medium-high heat. Once hot, place the salmon skin-side down and sear for 3-4 minutes until the skin is crisp. Flip the salmon and cook for an additional 2-3 minutes until the salmon reaches your desired doneness.
In the last 5 minutes of the sweet potato roasting, add the asparagus to the baking sheet to roast together.
Once everything is cooked, drizzle lemon juice over the seared salmon. Plate the salmon alongside the roasted sweet potatoes and asparagus.
Serve immediately and enjoy your balanced, nutrient-packed dinner.
