Brush melted butter on a cookie sheet and preheat your oven to 450°F.
In a large mixing bowl, combine all of your filling ingredients and mix well.
Layer your tortillas around the outside of your baking sheet. Place two tortillas in the center of your baking sheet. You should have your tortillas overlapping and also hanging off of the edge of the pan so you can fold the tortilla over the top of the filling.
Next, place your filling on top of the tortillas and spread it out evenly.
Fold the tortilla over and brush butter on top.
Place another cookie sheet on top of the quesadilla to hold the folded tortilla down and to keep it from burning.
Bake for 25 minutes or until the tops are golden and crispy.
Notes
Preheat your oven: Make sure your oven is preheated to the correct temperature before you start baking your quesadillas. This will ensure that they cook evenly and are fully cooked through.
Don't overfill your quesadillas: While it can be tempting to stuff your quesadillas full of ingredients, this can actually make them harder to cook and less flavorful. Stick to a moderate amount of filling to ensure that your quesadillas are easy to handle and packed with flavor.
