The best sandwich in the world!!!

 Well, must admit that I love to eat, taste every flavor if it is possible, every new and exotics combinations, but today I will talk about one of the most popular sandwich (and no, isn't about barros lucos).
I'm gonna talk about the famous, tasty and incomparable Chacarero. How not love that sandwich, must admit that is sold in many parts in Chile and not all of them follows an unique recipe, but every must agree that it has beef tenderloin (can be pork too), tomato slices, green beans, mayonnaise and green chili.
The difference can be the size of the sandwich, some places use their one mayonnaise recipe (some homemade versions or with garlic powder), also you can add that chilean american sauce (yeap sounds confusing), but some people goes far and instead of beef or pork tenderloin, goes with chicken breast or the vegetarian version with corn and cheese or the vegan one with humus, avocado, etc....
In my opinion I like the classic one, my younger version of me could stand with no problem the green chili, but my "mature" me has a picky stomach and have to order without the delicious green chili (sad face) and barely can stand "homemade version" of some locals, so I need to have me "safe places" to order chacareros.
