Preheat over to 350 degrees.
In a large bowl mash together the bread and milk until it forms a paste then mix in the egg.
Next add the ground turkey, sausage, italian seasoning, granulated garlic, onion powder, red chili flakes, salt, black pepper, grated parmesan/romano cheese, and breadcrumbs.
Using your hands mix the ingredients until everything is distributed evenly.
Portion out the meat mixture into 24 meatballs. I used a cookie scoop for this but you can also measure out 2 tablespoons of mixture per meatball. Please note this might change the amount of meatballs you end up with.
Cut up the cheese sticks into 5 pieces each. Place one piece into the center of each meatball and then roll it into a ball making sure to cover the cheese completely.
Bake for 25 minutes. Serve hot. If you choose you could place the meatballs in sauce to serve with pasta. The mozzarella will stay put in the meatballs.
