We will be on the dining plan for the first time next year and I noticed items like chili cheese fries, biscuits and gravy, soups...etc on the list for snack choices. How big are they? For example, we have a lot of dinner reservations for later in the evening and I am thinking that the chili cheese fries would be a good snack to tie us over until dinner. Is it big enough that a 4 and 7 year old could share? TIA!
