In a bowl, combine ground chicken, breadcrumbs, Parmesan cheese, egg, minced garlic, oregano, salt, pepper, lemon zest, and lemon juice. Mix well and form into meatballs.
Place meatballs on a baking sheet and bake for 20-25 minutes or until cooked through.
In a saucepan, bring chicken broth to a boil. Add orzo and cook according to package instructions. Drain if necessary.
Serve the baked meatballs over the lemon orzo and garnish with fresh parsley.
