In a large mixing bowl, add ground turkey, red onion, garlic, parsley, dill, breadcrumbs, egg, feta, lemon juice, lemon zest, oregano, salt, and pepper. Mix gently using your hands or a spoon until everything is evenly combined. Stop mixing once it holds together to keep the texture light and tender.
Shape the mixture into small meatballs, about 1 to 1½ inches in size. Place them on a baking tray lined with parchment paper, leaving a little space between each one so they cook evenly.
Bake in a preheated oven at 400°F (200°C) for 15–18 minutes, or until the meatballs are fully cooked and lightly golden on the outside.
While the meatballs are baking, prepare the salad. In a medium bowl, mix cucumber, tomato, red onion, parsley, lemon juice, olive oil, salt, and pepper. Stir well, taste, and adjust seasoning if needed. Keep chilled until serving.
Build your bowl by adding cooked rice or your favorite grain, then top with meatballs, cucumber tomato salad, tzatziki, feta, and kalamata olives. Serve warm and fresh.
