Preheat your oven to 425°F.
In a bowl, mix the lean ground turkey with garlic powder, onion powder, salt, and black pepper until well combined.
Shape the seasoned turkey into a patty that will approximate 6 ounces in weight.
Place the turkey patty on a lightly greased baking tray or cast iron skillet.
Wash the sweet potato and cut it into wedge-shaped pieces. In a separate bowl, toss the wedges with olive oil, a pinch of salt, and pepper.
Arrange the sweet potato wedges on another baking sheet, ensuring they are spread out in a single layer.
Place both the turkey patty and the sweet potato wedges in the oven. Bake the turkey patty for about 18-20 minutes or until cooked through, and the sweet potato wedges for 20-25 minutes, flipping halfway through, until they are crisp on the edges.
Once cooked, serve the lean turkey burger with a side of crispy baked sweet potato wedges and enjoy a healthy, well-balanced meal.
