01 - Preheat oven to 400°F. Line a baking sheet with parchment paper or lightly grease with olive oil.
02 - In a large bowl, gently mix ground turkey, breadcrumbs, Parmesan, egg, milk, green onions, garlic, oregano, salt, pepper, and chopped parsley until just combined.
03 - Using damp hands, shape mixture into 1-inch spheres and arrange evenly on the prepared baking sheet.
04 - Lightly brush meatballs with olive oil. Bake for 18 to 20 minutes, turning once halfway, until golden brown and cooked through.
05 - While meatballs bake, whisk barbecue sauce, honey, soy sauce, apple cider vinegar, and Dijon mustard in a saucepan over medium heat. Simmer 3 to 4 minutes until slightly thickened.
06 - Transfer baked meatballs to a large bowl. Pour warm glaze over them and toss gently to coat evenly.
07 - Place glazed meatballs on a serving platter, garnish with extra chopped parsley if desired, and serve warm with cocktail picks.
