Preheat and prep: Heat your oven to 400°F (200°C).
Line a sheet pan with parchment and lightly oil it.
Mix the meatballs: In a large bowl, combine ground turkey, egg, breadcrumbs, Parmesan, parsley, garlic, onion powder, paprika, salt, and pepper. Stir gently until just combined. Avoid overmixing to keep the meatballs tender.
Shape: Use a tablespoon or small scoop to form 20–24 meatballs.
Lightly oil your hands to prevent sticking and roll them evenly.
Bake: Arrange meatballs on the prepared pan. Brush or spray with olive oil. Bake for 14–18 minutes, or until the centers reach 165°F (74°C) and the edges are lightly browned.
Cook your base: While the meatballs bake, prepare your grains according to package directions.
Fluff and season with a pinch of salt.
Make the sauce: Stir together Greek yogurt, olive oil, lemon juice, grated garlic, herbs, salt, and pepper. Thin with a splash of water if needed for drizzling.
Prep toppings: Dice cucumber, halve tomatoes, slice onion, and cut avocado if using. Squeeze a little lemon over the avocado to reduce browning.
Assemble bowls: Add a scoop of grains, a handful of greens, 4–5 meatballs, and your veggies.
Spoon on the yogurt sauce and finish with fresh herbs and a squeeze of lemon.
Taste and adjust: Add more salt, pepper, or lemon to balance the flavors. A pinch of red pepper flakes is great if you like heat.
