Hopefully, ChefDenny will aid in this.
A walking Taco is so named because it's sold mainly at sporting events...like a track meet.
You take a small bag of Doritos and crush in the bag some
Cut the side off the bag.
Add taco seasoned meat.
Add all other taco condiments you like
such as lettuce
halopenos( however you spell it)
Then eat with a fork out of the bag.
Basically a taco without the hardshell as the holder.
