My 4 are grazers, so you betcha we bring snacks! We drive and bring a cooler, so I freeze juice boxes, yogurt tubes etc. to fill it up and keep it cold for the drive. We don't buy a lot of pre-packaged or single serving things at home, we save them for camping or vacations. We bring: The little single serve cereals, the ritz crackers that already have PB or cheese on them, cheese strings, pepperoni sticks, yogurt tubes, apple sauce squishers, lunchables (mostly for the drive), individual bags of goldfish, and 100 calory packs.
