I like a big juicy taco, a traditional Mexican dish composed of a corn or wheat tortilla folded or rolled around a filling.
I really like eating breakfast tacos with brisket or something. Do you know when they were invented?
 The origins of the taco are not precisely known, although their modern version can be traced to the last century.
Well thats kind of interesting that it is fully know. I'm assuming that they're still from Mexico? Or just South America?
The taco has spread throughout the region, but is still primarily a traditional Mexican dish composed
Are there any other cool traditional Mexican dishes? 
There are many dishes made from native foods, such as corn, beans, squash, amaranth, chia, avocados, tomatoes, tomatillos, chocolate, vanilla, agave, turkey, sweet potato, cactus, and chili pepper.
I love eating avocados, especially on some homemade fajitas. 
Which type of fajitas?    They now include chicken, pork, shrimp, lamb, salmon, and all other cuts of beef, as well as vegetables instead of meat.
Oh I didn;t know they came in so many flavors. My faorite is beef but I would love to try lamb and salmon.
