Cheese and tomato quesadilla

1. Spray a large pan or griddle with olive oil (or coat with ½ tablespoon of oil or butter). Heat on medium-high for 2 minutes, then add the tortilla. Warm for 30 seconds, then add the cheese and tomato to one half of the tortilla. Fold over the other half and press down with a spatula. 
2. Cook for 4-5 minutes, flipping halfway through, until the tortilla becomes lightly browned. Use a spatula to press down on the tortilla as it cooks to help the ingredients stick.
3. Remove from the pan and let cool for a few minutes before slicing.
