Preheat your oven to 425°F.
Toss the asparagus with 1 teaspoon of olive oil, a pinch of salt, and black pepper. Spread them in a single layer on a baking sheet.
Roast the asparagus in the preheated oven for about 12-15 minutes until tender and slightly crispy.
Meanwhile, pierce the sweet potato with a fork and microwave on high for about 5-7 minutes until soft, or bake it wrapped in foil in a preheated 400°F oven until tender. Once done, peel and mash in a bowl with 1 teaspoon olive oil, garlic powder, and a pinch of salt.
Season the salmon fillet with salt, black pepper, and a light sprinkle of garlic powder.
Heat a non-stick skillet over medium-high heat. When hot, place the salmon skin-side down (if it has skin) and sear for about 3-4 minutes until golden, then flip and cook for another 3-4 minutes until just cooked through.
Plate the seared salmon alongside a serving of roasted asparagus and a generous scoop of sweet potato mash. Enjoy immediately.
