- Preheat your oven to 400°F. 
- In a large bowl, combine ground chicken, breadcrumbs, Parmesan cheese, parsley, oregano, garlic powder, salt, pepper, and egg. Mix until well combined. 
- Form the mixture into meatballs, about 1 inch in diameter. 
- Place the meatballs on a baking sheet lined with parchment paper. 
- Drizzle olive oil over the meatballs and bake for 20-25 minutes, or until cooked through and golden brown. 
- While the meatballs are baking, bring chicken broth to a boil in a medium saucepan. 
- Add orzo and cook according to package instructions, usually about 8-10 minutes. 
- Once cooked, drain any excess liquid and stir in lemon zest, lemon juice, cherry tomatoes, and feta cheese. 
- Serve the meatballs over the lemon orzo, garnished with additional parsley if desired.
