When making the meatballs, you may run into the problem of them not binding or rolling well because it's just meat. Chicken doesn't hold a shape as well as pork or beef without help sometimes. You can add 1 large egg and a 1/4 cup of breadcrumbs to help bind if you prefer. I just wanted to keep this recipe as simple as possible so I didn't do this step. I went with free formed meatballs that weren't perfectly round. Either method will work just fine!
