How to cook mexican food

When i worked in a supermarket years ago, i met a lot of american people the loved mexican food, even mi manager used to send me to the kitchen to cook for him, so there is where i figure out is not easy to find a good place to eat authentic food. I have over 1 million  subscribers in mi spanish channel and decided to go to another level, as i always say my english is not the best, but i try, have a nice day.
