Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Peel the sweet potato and cut it into 1-inch thick wedges.
Place the sweet potato wedges on the baking sheet, drizzle with 0.5 tablespoons of the olive oil, and sprinkle with half of the sea salt and black pepper.
Roast the sweet potatoes in the oven for 15 minutes to ensure they become soft and tender.
While the potatoes roast, season the chicken breast on both sides with the garlic powder, dried oregano, and the remaining sea salt and black pepper.
Remove the pan from the oven, move the potatoes to one side, and place the chicken breast and broccoli florets on the other side.
Drizzle the broccoli with the remaining 0.5 tablespoons of olive oil.
Return the pan to the oven and roast for an additional 18 to 20 minutes until the chicken is cooked through and the potatoes are caramelized.
Let the chicken rest for 5 minutes before slicing to keep it juicy and flavorful.
