quesadilla

noun in spanish. This is a typical Mexican food thats consists of a tortilla folded in half filled with, compulsorily but not exclusively, cheese of any kind.

It is a word created in composition, combining the words queso (cheese) and tortilla (shortened as "dilla"), so it's clear that cheese is fundamental in this dish.

Person A: what you got there, pal?
Person B: a quesadilla
Person A: bruh, no cheese, no quesadilla. That's just a taco.

Person B: oh! you're right! hahaha
