Preheat your oven to 400°F (200°C) for even cooking and a golden color.
In a large mixing bowl, combine ground chicken or turkey, breadcrumbs, egg, sun-dried tomatoes, feta, parmesan, garlic, green onions, parsley, salt, and pepper.
Mix all ingredients until just combined; avoid overmixing to keep meatballs tender.
Using a cookie scoop or hands, portion mixture into 1 to 1.5-inch meatballs and place on a lined baking sheet.
Bake for 20-25 minutes until golden brown and internal temperature reaches 165°F (75°C).
Remove from oven and let cool for a few minutes before serving, optionally with a squeeze of lemon on top.
