In a large bowl, combine ground chicken, ricotta cheese, Parmesan cheese, breadcrumbs, egg, minced garlic, lemon juice, lemon zest, oregano, salt, and pepper. Mix until well combined.
Preheat your oven to 400°F. Line a baking sheet with parchment paper.
Form the mixture into meatballs, about 1.5 inches in diameter, and place them on the prepared baking sheet.
Drizzle olive oil over the meatballs and bake for 20-25 minutes, or until they are 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.
Drain the orzo and return it to the pot. Stir in a tablespoon of olive oil and season with salt and pepper to taste.
Serve the meatballs over the garlic orzo, garnished with fresh parsley and lemon wedges on the side.
