Grate the cheese using a grater until you have about 2 cups of shredded cheese, set aside.
Prepare your spooky fillings by cooking and shaping ingredients like chicken or veggies into fun shapes; set aside.
Preheat your skillet over medium heat and add a splash of oil to coat the bottom.
Lay a large flour tortilla flat in the skillet, then sprinkle a thin layer of shredded cheese over half of it, followed by your spooky fillings and a dash of chili powder or paprika.
Fold the tortilla over the fillings, pressing gently to seal the edges.
Cook for about 2-3 minutes until the bottom is golden brown and the cheese begins to melt, with bubbling around the edges.
Carefully flip the quesadilla using a spatula and cook for another 2 minutes until crispy and the cheese is fully melted.
Remove the cooked quesadilla from the skillet and let it rest for a minute to settle the cheese.
Use a cookie cutter or a sharp knife to cut the quesadilla into fun Halloween shapes like ghosts or pumpkins.
Serve immediately while crispy and cheesy, perfect for spooky season snacking.
