Preheat oven to 400°F (200°C) and line a baking sheet with parchment paper.
Grate the zucchini and place it in a clean kitchen towel; squeeze firmly to remove as much liquid as possible.
In a large mixing bowl, combine the ground turkey, squeezed zucchini, feta, breadcrumbs, egg, garlic, oregano, dill, salt, and pepper.
Mix gently until ingredients are evenly distributed, being careful not to overwork the meat.
Scoop and roll the mixture into 1.5-inch meatballs, yielding approximately 16 to 20 balls.
Arrange the meatballs on the prepared baking sheet with at least 1 inch of space between them.
Bake for 20 to 25 minutes, or until the internal temperature reaches 165°F (74°C) and the surfaces are lightly browned.
