Walking Taco's

Walking Tacos everywhere we eat the at my school and buy them at the stores. Walking tacos are so good they taste like a taco but they are in a bag. You can have them with chicken or beef and all the veggies. They sit in a bag on a tray for a yummy snack.Walking tacos are so good and are a lunch favorite.
