01 - Preheat oven to 400°F. Line a baking tray with parchment paper or lightly grease with oil.
02 - Heat 1 tablespoon olive oil in a skillet over medium heat. Sauté diced onion for 3–4 minutes until softened. Add minced garlic and cook for 1 minute more. Allow mixture to cool slightly.
03 - In a large mixing bowl, combine ground chicken, sautéed onion and garlic, chopped sage, thyme, salt, pepper, and optional nutmeg.
04 - Incorporate breadcrumbs and lightly beaten egg. Gently mix until just combined, ensuring not to overmix.
05 - With damp hands, form the mixture into balls, using approximately 1 heaping tablespoon each. Arrange evenly on the prepared tray.
06 - Brush or drizzle the remaining olive oil over the balls. Bake for 20–25 minutes, turning halfway, until golden brown and cooked through (internal temperature should reach 165°F).
07 - Serve hot, accompanied by your preferred dipping sauce or as part of a meal.
