Filled with Swiss cheese, caramelized onions, and mushrooms, Aidells Portobello & Swiss Cheese Smoked Chicken Sausage is all-natural, fully cooked, gluten-free and has no added nitrites, except for those naturally occurring in celery powder. Includes one 3 lb. package of 15 links. For over 30 years, Aidells chicken sausages have been handcrafted in small batches with care using only the freshest, most flavorful ingredients we can find. Made with real fruits and vegetables such as apples, mangoes, sun-dried tomatoes, and real garlic, our all-natural sausages are stuffed by hand in natural casings and slow-smoked for hours over real hardwood chips for that snap we love. And you’ll never find anything you can’t recognize in our sausage because we never use any fillers or binders, ever. Though the Aidells brand has grown over the years, we still believe in doing things the way we always have: with extraordinary care and passion. Minimally processed, no artificial ingredients
