In a bowl, blend together cheese, cream cheese, and salsa.

Divide and spread cheese mixture over 4 of the tortillas.  Top with the remaining tortillas creating 4 quesadillas.

Brush one side of each quesadilla with melted butter.

In a skillet, fry tortilla butter side down.  Brush other side with melted butter.

Fry quesadilla until one side is crisp and brown.  Flip and cook the other side until crisp and brown.  Continue this process until all the quesadillas are cooked on both sides just like a grilled cheese sandwich.

Slice each quesadilla into 4 wedges with a pizza cutter and serve with additional salsa.  Makes 4-6 servings.
