One of the best portable snacks is definitely apples. You don’t have to refrigerate them and you can eat them on-the-go. An apple is around 85% water, so it’s a good way to fill your stomach and slake your thirst at the same time. There are over 7,500 varieties of apples grown around the world. I personally like Pink Ladies and Granny Smiths. And what’s your favorite kind of apples?
