Preheat your oven to 400°F.
Lightly season the salmon fillet with salt, pepper, and a pinch of garlic powder.
Heat a non-stick skillet over medium-high heat. Once hot, add a small amount of olive oil and sear the salmon for about 3-4 minutes on each side until a golden crust forms. Remove from the skillet and set aside.
While the salmon is searing, prepare the asparagus by tossing them with a drizzle of olive oil, salt, and pepper. Spread them evenly on a baking sheet.
Roast the asparagus in the preheated oven for about 10-12 minutes until they are tender and slightly caramelized.
Peel the sweet potato and cut it into small cubes. Boil them in water until soft, about 10 minutes.
Drain the sweet potato and mash them using a fork or potato masher. Stir in the nonfat Greek yogurt, and season with salt and pepper to taste, until you reach a creamy consistency.
Plate the dish by placing a generous scoop of sweet potato mash on the side, arranging the roasted asparagus, and topping with the seared salmon fillet.
Serve immediately and enjoy your nutrient-packed dinner.
