01 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
02 - In a large bowl, combine ground turkey, breadcrumbs, Parmesan, egg, garlic, parsley, oregano, salt, and pepper. Mix until just combined.
03 - Form the mixture into 16 small meatballs (about 1 tablespoon each) and place on the prepared baking sheet.
04 - Spray meatballs lightly with olive oil. Bake for 15–18 minutes, or until cooked through and golden.
05 - Meanwhile, warm the marinara sauce in a small saucepan over medium heat.
06 - Once the meatballs are cooked, add them to the saucepan and toss to coat with marinara sauce.
07 - Lay out tortillas and sprinkle half the mozzarella cheese down the center of each.
08 - Divide the saucy meatballs evenly among the wraps (4 per tortilla). Top with onions, spinach, and remaining cheese.
09 - Fold in the sides and roll up the wraps tightly.
10 - Toast the wraps in a dry skillet over medium heat for 2–3 minutes per side, until golden and the cheese melts.
11 - Slice in half and serve warm.
