Preheat your oven to 425°F. Peel and cube the sweet potato into 1-inch pieces.
Place the sweet potato cubes on a baking sheet, drizzle with olive oil, and season with salt and pepper. Toss to coat evenly.
Roast the sweet potatoes in the oven for about 25-30 minutes, until tender and slightly caramelized.
Meanwhile, trim the woody ends off the asparagus. Toss them lightly with salt, pepper, and a touch of olive oil, then set aside.
Season the salmon fillet with salt and pepper. Heat a non-stick skillet over medium-high heat and sear the salmon, skin side down if applicable, for about 4-5 minutes. Flip and cook for another 3-4 minutes until cooked through.
In the last 8 minutes of the sweet potatoes’ roasting time, add the asparagus to a separate baking tray and roast them in the oven until they are tender and lightly browned.
For the sauce, in a small bowl, mix the nonfat Greek yogurt with the juice of 1/2 lemon, fresh dill, and a pinch of salt and pepper.
Plate the seared salmon alongside the roasted sweet potatoes and asparagus. Drizzle the lemon-dill yogurt sauce over the salmon or serve on the side.
Serve warm and enjoy your balanced, nutrient-rich dinner.
