Step 1

Place the first 6 ingredients in a large bowl; toss to combine. To assemble, lightly brush the tops of 2 tortillas with 1/2 teaspoon oil; turn over. Top with cheese mixture and remaining tortillas. Brush tops with remaining oil.

Step 2

Place a large nonstick skillet over medium heat. In 2 batches, cook quesadillas 1-2 minutes on each side or until golden brown and cheese is melted. Cut each quesadilla into 6 wedges. If desired, serve with guacamole.
