Preheat your oven to 400°F. Peel and cube the sweet potato into even pieces, and trim the ends of the asparagus.
Place the sweet potato cubes and asparagus on a baking sheet, drizzle lightly with a bit of olive oil, and season with salt, pepper, and garlic powder.
Roast the vegetables in the oven for about 20-25 minutes, or until the sweet potatoes are tender and the asparagus are slightly crispy.
While the vegetables roast, pat the salmon fillet dry with paper towels and season generously with salt and pepper.
Heat a non-stick skillet over medium-high heat and add the olive oil. Once hot, carefully place the salmon skin-side down (if applicable) and sear for about 4-5 minutes until a golden crust forms.
Flip the salmon carefully and cook for an additional 3-4 minutes, or until the salmon is cooked to your preferred level of doneness.
In a small bowl, mix together the nonfat Greek yogurt, lemon juice, fresh dill, and a pinch of salt to create a refreshing sauce.
Plate the seared salmon alongside the roasted sweet potato and asparagus, and drizzle the yogurt dill sauce over the salmon or serve it on the side.
Serve immediately and enjoy your balanced, nutrient-packed dinner.
