Etymology

Origin of quesadilla

First recorded in 1940–45; from Mexican Spanish; Spanish: “a pastry or cake made with cheese,” equivalent to quesada ( queso “cheese,” from Latin cāseus; cf. cheese 1 + -ada noun suffix) + -illa diminutive suffix; see -ade 1

Explanation

Next time you go to a Mexican restaurant, you might want to order a quesadilla, a grilled tortilla filled with melty cheese. Quesadillas come on flour or corn tortillas, which are loaded with cheese and sometimes vegetables or meat, and cooked over high heat. In Mexico, a quesadilla is traditionally made with Oaxaca cheese inside a folded corn tortilla, which is grilled without oil and served with salsa. There are many variations of this popular dish. Quesadilla comes from the Spanish queso, "cheese."
