Preheat the air fryer to 400°F.
Peel and cube the sweet potato into half-inch pieces, then toss them in a bowl with olive oil, sea salt, black pepper, and garlic powder.
Spread the seasoned potatoes in the air fryer basket and cook for 10 minutes, shaking the basket halfway through.
Crumble the ground chicken into the basket over the potatoes and add the broccoli florets.
Air fry for another 8-10 minutes, stirring occasionally to break up the chicken, until the meat is cooked through and the broccoli is tender-crisp.
In a small mixing bowl, whisk together the buffalo hot sauce, lime juice, and apple cider vinegar.
Transfer the chicken, potato, and broccoli mixture to a large bowl and pour the spicy tangy glaze over the top, tossing well to coat.
Garnish with fresh sliced green onions and serve immediately.
