Preheat your oven to 425°F.
Peel and cube the sweet potato into 1-inch pieces. Toss with a pinch of salt, pepper, and a drizzle of olive oil. Spread the cubes evenly on a baking sheet.
Trim the ends of the green beans and toss them lightly with a pinch of salt and pepper on another baking sheet or with the sweet potatoes if space allows.
Place the sweet potatoes in the oven and roast for about 20-25 minutes, turning once halfway through, until tender and slightly caramelized.
About 10 minutes before the sweet potatoes are done, add the green beans to the oven if using a separate tray (or add them to the same tray if there’s room), and roast until they are crisp-tender.
While the vegetables are roasting, season the salmon fillet with salt and pepper on both sides.
Heat a non-stick skillet over medium-high heat. Once hot, add the salmon fillet skin-side down (if it has skin) and sear for 3-4 minutes until the skin is crisp.
Flip the salmon carefully and cook for another 3-4 minutes, depending on thickness, until the salmon is just cooked through and flakes easily with a fork.
Plate the salmon with a serving of roasted sweet potato cubes and green beans. Enjoy your balanced, easy meal!
