Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Slice the sweet potato into even wedges and chop the bell pepper into thick strips.
In a large bowl, toss the sweet potato wedges and bell peppers with half of the olive oil, sea salt, black pepper, and the smoked paprika.
Season the chicken breast with the remaining olive oil, garlic powder, and dried oregano, ensuring it is evenly coated.
Arrange the sweet potato wedges in a single layer on the baking sheet, leaving space for the chicken breast and peppers.
Place the chicken on the sheet and roast for 20-25 minutes, flipping the wedges halfway through, until the chicken reaches an internal temperature of 165°F.
Remove from the oven, slice the chicken into strips, and serve immediately alongside the crispy wedges and peppers.
