Step 1: Preheat your oven to 400°F (200°C) to create a golden crust on the meatballs.
Step 2: In a large mixing bowl, combine the ground chicken and bratwurst (after removing the casing). Mix thoroughly.
Step 3: Add the chopped onion, lemon zest, mint, parsley, chives, and basil. Season with salt and pepper, then mix gently.
Step 4: Shape the mixture into meatballs about 1 to 1.5 inches in diameter. Use flour if needed to prevent sticking.
Step 5: Drizzle olive oil over the meatballs for flavor and browning.
Step 6: Bake in the preheated oven for 20-25 minutes or until the internal temperature reaches 165°F (74°C).
Step 7: Let the meatballs rest before serving. Enjoy them on their own or with pasta!
