Preheat the oven to 400°. Place the bread in a food processor, and pulse 10 times to make coarse crumbs to measure 1 cup.
Combine cilantro, dill, and parsley in a small bowl. Combine breadcrumbs, 4 1/2 tablespoons herb mixture, turkey, and next 8 ingredients (through garlic) in a large bowl. Shape into 46 (1-inch) meatballs.
Spread 2 tablespoons oil over bottom of a jelly-roll pan; arrange meatballs in a single layer, and turn lightly to coat. Bake 15 minutes or until done, turning once. While hot, sprinkle with remaining herbs. Serve hot or at room temperature with Yogurt-Cucumber Dip.
