Travel Tip: Backup Foods to Carry for Vegetarians - as part of the expert series by GeoBeats. Some foods that I like to pack as a backup in case that I do not find any vegetarian or vegan options while traveling are Powdered Miso soups because they come in little packets and they do not take up much room in my suitcase. I always bring a powdered green drink that has a full six servings of vegetables per packet, I just pop it in my water bottle and I am good to go for the day. And another thing that is great are bars, protein bars, snack bars, so that you always have something to snack on in between meals.
