You can use a frying pan or toaster for the dish. I fried mine in the pan.
Turn on the heat of the pan.
Cut onion, tomato, and bell pepper into smaller pieces.
Place your tortilla on the kitchen counter.
Use scissors to cut it from the center outward.
Place the cut hole downward towards yourself.
Put filling in the part closest to you on the right side.
Continue filling the next section on the right side.
Repeat for the last two sections.
Now fold the first layer on the right side up over the second layer on the right side.
Then fold it to the left and finally over the last layer.
Now you have something that looks like a nice fan.
Fry it in the pan or toaster. If using a pan, make sure to flip it.
The dish is ready when the wrap is crispy on both sides and the cheese is melted.
Bon appétit.
