01 - Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper or lightly grease it with olive oil.
02 - In a large mixing bowl, combine the ground turkey, egg, grated zucchini, grated carrot, finely chopped onion, minced garlic, and chopped parsley.
03 - Add the breadcrumbs, grated Parmesan cheese (if using), dried oregano, salt, black pepper, and paprika to the bowl. Gently mix until all ingredients are just combined; avoid overmixing.
04 - Using lightly dampened hands, shape the mixture into uniform meatballs, approximately the size of a golf ball, yielding about 20-24 pieces. Arrange them on the prepared baking sheet.
05 - Lightly drizzle or brush the tops of the meatballs with olive oil.
06 - Bake for 20-25 minutes, or until the meatballs are golden brown and fully cooked through. The internal temperature should reach 165°F (74°C).
07 - Serve the meatballs hot, accompanied by your preferred sauce, or alongside whole grains or pasta.
