Preheat the oven to 400°F and line a large sheet pan with parchment paper or lightly grease it.
In a mixing bowl, combine the ground turkey, 1/4 cup barbecue sauce, breadcrumbs, egg, onion, garlic, salt, and black pepper. Mix until just combined, then shape into 8 small oval meatloaves and place them on one side of the sheet pan.
In a separate bowl, toss the sweet potato wedges with olive oil, smoked paprika, and a pinch of salt. Spread them on the other side of the sheet pan.
Scatter the corn kernels around the sweet potatoes and meatloaves on the pan.
Brush the remaining 1/4 cup barbecue sauce over the tops of the meatloaves.
Bake for 25 to 30 minutes until the meatloaves reach an internal temperature of 165°F and the sweet potatoes are tender.
Remove from the oven and sprinkle with chopped parsley before serving.
