Cemita refers to Mexican version of sandwich which is actually a serving of a giant roll, covered with fresh avocado and then filled with meats, beans, cheese, chili and other spices of your choice. Cemita best when eaten with a little bowl of Gazpacho, a Mexican cold tomato-and-cucumber-based soup. Cemita is one of Mexico's popular street food aside from Esquites, Guacamole, Chalupa and many others. Throughout Mexico, many street vendors offer equally delicious eating options as in the restaurants.
