Preheat your oven to 400°F and line a baking sheet with parchment paper.
Peel and cut the sweet potato into uniform wedges or cubes.
Toss the sweet potatoes with half of the olive oil, salt, and pepper, then spread them on the baking sheet.
Roast the sweet potatoes for 20 to 25 minutes until they are tender and slightly browned.
Trim the ends of the green beans and steam them for 5 to 7 minutes until they reach a tender-crisp texture.
In a medium bowl, combine the ground turkey with garlic powder, dried oregano, salt, and pepper.
Form the turkey mixture into two even patties, being careful not to overwork the meat.
Heat the remaining olive oil in a non-stick skillet over medium-high heat.
Sear the turkey patties for 5 to 6 minutes per side, or until the internal temperature reaches 165°F.
Serve the seared patties alongside the roasted sweet potatoes and steamed green beans while hot.
