Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper for easy cleanup.
Wash and scrub the sweet potato, then slice it lengthwise into uniform wedges and toss them in a bowl with the olive oil, smoked paprika, and half of the sea salt.
Spread the sweet potato wedges in a single layer on the baking sheet and roast for 25-30 minutes, flipping halfway through, until they are tender and caramelized.
While the potatoes roast, season the chicken breast with garlic powder, the remaining sea salt, and black pepper, then grill or pan-sear over medium-high heat for 6-7 minutes per side until fully cooked.
In a small mixing bowl, combine the Greek yogurt, lemon juice, and finely chopped fresh parsley to create a bright and zesty dipping sauce.
Slice the cooked chicken into thin strips and serve immediately alongside the warm roasted wedges and the creamy yogurt dip.
