Cook the base: Prepare rice or quinoa according to package directions. Fluff and set aside. For extra flavor, stir in a squeeze of lemon and a drizzle of olive oil.
Make the yogurt sauce: In a small bowl, mix Greek yogurt, lemon juice, grated garlic, dill, olive oil, salt, and pepper.
Taste and adjust. Chill while you cook the meatballs.
Mix the meatballs: In a large bowl, combine ground turkey, breadcrumbs, egg, garlic, red onion, parsley, oregano, cumin, lemon zest, salt, and pepper. Mix gently with a fork or your hands until just combined.
Shape: Scoop into 1 to 1.5-inch balls.
You should get about 16–18 meatballs. Lightly oil your hands to keep the mixture from sticking.
Cook the meatballs: Heat 1–2 tbsp olive oil in a large skillet over medium heat. Add meatballs in a single layer.
Cook 8–10 minutes, turning every couple of minutes, until browned on all sides and cooked through. Internal temperature should reach 165°F (74°C).
Prep the veggies: While the meatballs cook, dice cucumber, halve tomatoes, slice red onion, and pit/halve the olives.
Build the bowls: Add a scoop of rice or quinoa to each bowl. Top with meatballs, cucumber, tomatoes, onion, and olives.
Add a generous spoonful of yogurt sauce and sprinkle with feta and herbs. Finish with a light drizzle of olive oil and a splash of red wine vinegar or an extra squeeze of lemon.
Taste and adjust: Add more salt, pepper, or lemon if needed. Serve warm with extra sauce on the side.
