01 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
02 - In a large mixing bowl, combine ground turkey, breadcrumbs, egg, parsley, onion, garlic, salt, pepper, and thyme. Mix until just combined without overworking.
03 - Shape mixture into 20 to 24 small meatballs and arrange evenly on the prepared baking sheet.
04 - Bake for 15 to 18 minutes until meatballs are cooked through and lightly golden.
05 - While meatballs bake, whisk together cranberry sauce, honey or maple syrup, soy sauce, Dijon mustard, apple cider vinegar, and black pepper in a medium saucepan over medium heat. Simmer for 5 to 7 minutes, stirring occasionally, until glaze thickens slightly.
06 - Transfer baked meatballs to the saucepan and gently toss to coat in the cranberry glaze. Simmer for an additional 2 to 3 minutes to meld flavors.
07 - Serve warm, garnished with additional parsley if preferred.
