Preheat your oven to 425°F for roasting the asparagus and heating the sweet potato.
Start by piercing the sweet potato with a fork and microwave on high for 5-6 minutes until tender, or bake in the oven until soft.
While the sweet potato is cooking, heat a non-stick skillet over medium-high heat. Pat the salmon fillet dry, season with salt and pepper, and lightly brush with olive oil.
Sear the salmon on the skillet for about 3-4 minutes on each side until a golden crust forms and the inside is just opaque.
Place trimmed asparagus on a baking sheet, drizzle with a small amount of olive oil, and season with salt and pepper. Roast in the preheated oven for about 10 minutes until tender and slightly browned.
Once the sweet potato is softened, peel (if desired) and mash it in a bowl until smooth. Season with a pinch of salt and pepper.
Plate the dish by placing a portion of sweet potato mash on the plate, top with the seared salmon, and arrange the roasted asparagus on the side. Optionally, finish with a squeeze of fresh lemon juice over the salmon for brightness.
