Preheat the oven to 200ºC / 400ºF. Place lemon slices on a baking sheet. Dry the chicken wings thoroughly with paper towels, pressing down hard to remove as much excess moisture as possible.
Place the chicken wings in a large bowl. Set aside.
In a small bowl combine the melted butter or ghee, brown sugar (swerve), ginger powder, soy sauce, lemon and lime, garlic cloves, chili pepper, salt, black and cayenne pepper.
Pour this mixture over the wings and using your hands, toss well to coat. Spread the wings in a single layer on the prepared baking sheet.
Bake the wings until browned and crisp (45-50 minutes), using tongues to flip them over halfway.
Carefully remove wings from the oven and transfer them to a large serving platter. Sprinkle the wings with parsley. Serve with lemon and lime wedges.
