Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Peel the sweet potato and dice it into uniform 1/2-inch cubes to ensure even cooking.
Toss the sweet potato cubes on the baking sheet with half of the olive oil, half of the sea salt, and all of the smoked paprika.
Spread the potatoes in a single layer and roast for 20-25 minutes until they are tender and caramelized on the edges.
While the potatoes roast, combine the ground chicken, minced garlic, thinly sliced green onions, dried oregano, and the remaining salt and pepper in a mixing bowl.
Gently form the chicken mixture into two even-sized patties, being careful not to overwork the meat to keep them juicy.
Heat the remaining olive oil in a non-stick skillet over medium heat and sear the patties for 5-6 minutes per side until golden brown and cooked through.
Serve the hot chicken patties immediately alongside the roasted sweet potatoes for a clean and balanced meal.
