In a large bowl, combine the turkey, breadcrumbs, cranberries, parsley, thyme, salt, and pepper. Add the cooked vegetables, egg, and ⅓ cup of broth. Mix until everything is well combined. If the mixture feels dry, add a little more broth, 1 tablespoon at a time, until it holds together when pressed. Refrigerate the mixture for 20–30 minutes to firm up.
