i have both a vidalia and a ninja use the ninja almost everyday it is quick and easy and dishwasher safe.. i buy bulk carrots, onions and celery and bell peppers and chop them up and freeze them in cup containers usually using my shrink wrap but then i dont have to cut them again to make my casseroles and soups and stews i love it.. i dont have an idea on the cheese i buy mine ready shredded from costco sorry...i love the clean up ease with the ninja and they are not expensive i think about $30.
