'stache #34 - burrito moustache

For a truly mysterious 'stache with a south of the border flair, look no further than the burrito moustache. For centuries, the young and old have delighted in guessing the content of this 'stache, which historically could range from simple seasoned rice to all manner of pricy exotics. Indeed, burritostach guessing reached its peak in popularity in the 1940s, when no fewer than 35 burrito moustache mystery clubs could be found in the Mexico City phonebook. While x-ray technologies and flimsier burrito wrappers largely ended the craze, the burrito 'stache remains fun and mysterious.

For instance, can you guess the contents of the burritos pictured below? Chicken? Perhaps beef?

Sorry, friend. It’s halibut with mango salsa. You owe me 2 dollars.

Being relatively heavy, the burrito moustache is rarely worn outside of the home.
