Preheat the oven to 450F. Line a large baking sheet with foil and brush the foil lightly with some olive oil.
Add the turkey to a bowl, along with the feta, lemon zest, breadcrumbs, and egg. Use a fork to loosely mix the ingredients together.
Season with dill, 2 cloves garlic, cinnamon, salt, and pepper. Use your hands until the mixture is thoroughly combined.
Roll the meat mixture into small balls about 1 1/2” in diameter. As you finish each, place it in the baking sheet that you’ve prepared, about 1” apart.
When they are all finished, brush the tops with oil, and bake in the oven for about 15 minutes, until cooked through.
Finish them by placing them under the broiler for about 3 to 4 minutes.
Prepare the lemon yogurt sauce by whisking the lemon juice, remaining clove of garlic (minced), and yogurt together.
Garnish with parsley, and serve with flatbread and yogurt sauce.
