In a large bowl, combine ground chicken, breadcrumbs, feta cheese, parsley, minced garlic, oregano, egg, salt, and pepper. Mix gently until all ingredients are just combined.
Using your hands, shape the mixture into small meatballs, about 1 inch in diameter. You should get around 12-15 meatballs.
Heat a skillet over medium heat and add a drizzle of olive oil. Once hot, add the meatballs in a single layer. Brown them for about 4-5 minutes on each side until fully cooked and golden brown. Remove from skillet and set aside.
In the same skillet, add the vegetable broth and bring to a boil. Stir in the orzo and cook for about 8-10 minutes, or until al dente, stirring occasionally.
Once the orzo is cooked, add lemon zest, lemon juice, chopped dill, salt, and pepper. Mix well and cook for an additional minute to combine flavors.
On a plate, layer the lemon orzo and top it with the Greek chicken meatballs. Garnish with extra dill or lemon wedges if desired.
Notes
Be careful not to overmix the meatball mixture to keep them tender.
