Melt a small amount of butter in a large skillet over medium heat.

Place one tortilla in the skillet and sprinkle half a cup of cheese evenly over it.

Place a second tortilla on top. Cook for 2 to 3 minutes until the bottom is golden brown.

Carefully flip the quesadilla and cook the other side until golden and the cheese is melted.

Repeat with the remaining tortillas. Cut into wedges to serve.
