Fruit is one of the best on-the-go snack options out there. Berries are already naturally snack-sized and finger-friendly, as are grapes. Prepare fruit by washing and slicing it as needed before you start your trip. Store it in lidded food containers inside an insulated cooler to help keep it cool and fresh. While fresh fruits can be cubed, sliced or eaten whole, also consider single-serving containers of applesauce or dried fruits. Dried apricots, cranberries, raisins or whatever your favorite dried fruit may be can be a healthy part of your daily diet, as are fruit leathers. Keep in mind while snacking: One cup of fresh fruit equals half a cup of dried [source: Ray].
For less mess, avoid fruits that will leave you with waste to worry about, such as cherries or other fruits with pits.
