Heat oil in a large skillet on medium to medium-high heat. Add the flour tortilla and spread cheese all over the tortilla. Add meat to half of the tortilla, then use a spatula to flip the other half over to make a half-moon shape.

Cook the quesadilla 2-3 minutes, until browned. Flip and cook the other side about 2 minutes.

Remove the cooked quesadilla to a cutting board and allow to cool slightly before cutting.
