Cook chorizo on medium heat, once its half way cooked add all veggies. Once done remove from pan leave remaining oil in pan.

Fry tortillas one at a time in chorizo oil if you need to add a teaspoon of lard that is fine. you want them to be crunchy so they can hold the veggies without tearing.

When you are on the last tortilla and its almost done start layering the veggies mix and cheese. Add 2nd tortilla and repeat. Turn up heat to medium high and cover just till cheese melts.
