Preheat oven to 375°F. Line a baking sheet with parchment paper.
In a large bowl, gently stir together (I prefer to get in there with my hands) chicken, parsley, garlic, red onion, and red pepper. Set aside.
In a small bowl, whisk together evoo, white wine, egg yolks, and matzo meal. Add evoo mixture into chicken mixture and gently mix together. Do not compress the mix or meatballs will be tough. Season with salt and pepper. I recommend testing the seasoning by cooking a small piece of meat and tasting it.
Using moist hands or an ice cream scoop, scoop about 2 tablespoons of mixture and roll into a ball before placing onto prepared pan. Repeat with the rest of meat to make about 20 meatballs.
Heat another large baking sheet in preheated oven until very hot. Add several tablespoons of evoo to hot pan and transfer meatballs. Sear meatballs in oven, occasionally shaking the pan to rotate the meatballs (if need okay to flip with a spatula), until browned, about 10 minutes.
