In a small pan over medium-low heat, sprinkle all the grated cheese in the pan. Sprinkle the cheese to make a filled circle shape, and aim to make it a little bigger than the diameter of the tortilla.
Let the cheese melt for a couple of minutes.
When the cheese is melted and starts to look a little crispy, place the tortilla on top of the cheese. Let sit for a minute.During this minute, the cheese will stick to the tortilla. This also gives the tortilla some time to warm and soften up. Then use a spatula to flip it over (it should flip easily and no cheese should stick to the pan). Let the tortilla warm up on the other side for 30 seconds.
Then remove onto a plate. Fold it in half and eat right away! Enjoy ^_^
