Quesadillas

Little cheese things, this version with meat obviously. 

Quesadillas are Mexico's cheese sandwich snack food. Melted Mexican cheese inside a folded tortilla. The tortilla can be either flour or corn. The cheese needn't be necessarily Oaxacan. They are generally enhanced with chicken, chile, diced onions. They can be folded in half and then heated in a pan, or formed with two tortillas and then cut as a pizza, I've had them served simply cheese melted onto a corn tortilla and then rolled, but that was on a beach where the idea might have been to keep out sand. 

Masa rolled in preparation of being flattened ↓. 

I didn't have any fresh or tinned tomatoes so I used sun-dried tomatoes instead.

Diced onion and diced chile pepper mixed with ground beef.

Cheese melted in a table-top oven rather than in a pan.
