Preheat oven: Set to 400°F (205°C) and line a baking sheet with parchment paper.
Prepare meatballs: In a bowl, combine ground chicken, breadcrumbs, onion, garlic, oregano, paprika, salt, pepper, egg, and parsley. Mix until combined.
Shape meatballs: Form mixture into 16 small meatballs and place on the prepared baking sheet.
Bake meatballs: Cook 18–20 minutes until golden and fully cooked (internal temp 165°F / 74°C).
Cook the rice: In a medium saucepan, heat olive oil, add rice, and toast 2 minutes. Add chicken broth, lemon zest, and salt. Cover and simmer 15–18 minutes until rice is tender. Stir in lemon juice at the end.
Assemble bowls: Divide lemon rice into bowls, top with chicken meatballs, sprinkle with parsley, and add optional toppings.
