How do you make taco in a bag?

It's called a walking taco, for future references.

1. You take a small bag of Fritos ( or any corn chips )

2. You take the chips and crush them up.

3. You add the taco meat you have made into the bag.

4. You add lettuce, tomatoes, etc.

AND BOOM! Taco in a bag :)

Hope I helped!
