Families are busy and we need snacks we can pick up at the grocery store and run with. There are a lot of vegan grocery stores out there, but this list is for the ones that aren't. If I can find these treats in rural Newfoundland, Canada, you can find them too.
But always read the ingredients list just in case.
clif bars (even the chocolate chip ones are vegan!)
fresh and dried fruit/nuts
mini ritz crackers with peanut butter
jelly beans (without gelatin)
some potato chips
fruit/vegetable squeezie packets (ex. love child organics or baby gourmet)
This list is by no means extensive, and please remember that these snacks should be enjoyed in moderation.
