There is a lack of proper snack food at my parent’s place. However, if I got more I would not finish it before I leave. It cannot aggravate allergies and my father should be able to snack, too. So... I need snacks that are non-dairy, no wheat, corn or rice and someone with the use of only one hand can easily eat. They will eat, like, 5 or 6 grapes a day between them so those will spoil before they are eaten. Suggestions?
