Preheat your skillet over medium heat until warm, and prepare your ingredients for easy assembly.
Lay a tortilla flat on a cutting board and spread a thin layer of refried beans over half of it, then sprinkle generously with shredded cheese.

Use sliced black olives or beans to create eyes, placing them on the cheese layer, and add a strip of red bell pepper for a mouth, shaping a spooky face.

Top with another tortilla and gently press down to seal the edges, then carefully transfer the assembled quesadilla to the hot skillet.
Cook for about 3-4 minutes until the bottom is golden and crispy, then flip carefully using a spatula, listening for a satisfying crunch.
Cook the other side for another 3-4 minutes until golden brown and cheese is melted and bubbly inside.
Remove the quesadilla from the skillet and let it rest for a minute, then cut into wedges, revealing the gooey, cheesy interior and fun decorations.
Serve warm with optional toppings like sour cream, salsa, or guacamole for extra flavor and fun.
