In a large bowl, toss the sweet potatoes with 1 tablespoon of olive oil, garlic powder, smoked paprika, salt, and pepper. Spread them evenly on a baking sheet.
Roast the sweet potatoes for 20 minutes, stirring halfway through.
Meanwhile, toss the green beans with the remaining tablespoon of olive oil, salt, and pepper.
After 20 minutes, add the green beans to the baking sheet with the sweet potatoes, spreading them evenly.
Continue roasting for another 10-12 minutes, or until the sweet potatoes are tender and the green beans are slightly crispy.
Serve warm.
