Mexican food, in a nutshell:

A tortilla is either corn or wheat.
But a corn tortilla folded and filled is a taco,
whereas a filled wheat tortilla is a burrito.
Deep fry a burrito, it's a chimichanga.
Toast a tortilla, it's a tostada.
Roll it, it's an enchillada.
:
Your basic Tex-Mex food groups.
Cheese on top of chicken under guacamole
on top of beans under rice on top of beef.
Word of warning, avoid the jumbo prawns.
It's like Russian Roulette.
One in six will kill you.
