Preheat a griddle or skillet over medium low heat.
Assemble quesadillas. If using a spread, spread to cover the entire tortilla, but leave a small border around the edge.
Top half of the tortilla with shredded cheese, toppings, and additions to your taste. Fillings can also be mixed and then placed on tortilla. Fold in half.
Brush griddle or skillet with oil or melt butter. Once melted, add quesadilla. Cook until golden and toasty on one side and cheese is partially melted, 2-3 minutes. Carefully flip and cook on the other side for 2-3 minutes more or until tortilla is golden and toasty on both sides and cheese is melted.
Remove quesadilla carefully from pan. If cutting, allow to cool slightly. Serve with condiments to YOUR taste. Enjoy!
