Preheat the oven to 400°F.
Peel and cube the sweet potato, then steam or boil until tender for mash.
Lightly toss broccoli florets with olive oil, salt, and pepper; spread them on a baking sheet.
Roast the broccoli in the oven for about 15-20 minutes, until edges are slightly crispy.
Meanwhile, heat a non-stick skillet over medium-high heat. Season the salmon with salt, pepper, and garlic powder.
Sear the salmon fillet skin-side down for about 3-4 minutes, then flip and cook for another 3 minutes, or until desired doneness.
Mash the sweet potato with a fork or potato masher, adding a pinch of salt and pepper.
Plate the mashed sweet potato as the base, top with the seared salmon, and arrange the roasted broccoli on the side. Serve warm.
