In a large bowl, combine ground chicken, breadcrumbs, feta, parsley, dill, garlic, red onion, oregano, salt, pepper, lemon zest, and egg. Use your hands (it’s fun!) to mix everything until just combined.
Scoop out tablespoon-sized portions and roll into balls—about 20 meatballs.
Heat olive oil in a large skillet over medium heat. Add meatballs in a single layer (work in batches if needed). Cook for 8–10 minutes, turning occasionally, until golden and cooked through.
Pile onto a platter, squeeze a little lemon over the top, and sprinkle with extra herbs if you like. Enjoy with tzatziki, pita, or a simple salad!
