Useful snack

Today I need to be in the hospital for an appointment at 11.30 with mt 5 month old. I am trying to think of suitable snack to take for while we are waiting that will keep us both going. Most of the foods he eats at he moment are pretty messy so I'm not sure what to pick. Might have to resort to a sugar free bisuit for him (organix animal biscuits) and a banana and apple for me, and a pot of peanuts in the car just in case.
