Preheat large skillet over low heat. Line up six tortillas. Divide cheese, corn, cilantro and peppers between the tortillas, then cover each with a second tortilla. Place a tortilla on the dry skillet or grill and warm until cheese is melted and tortilla is slightly golden, about three minutes. Flip and cook other side until golden, about one minute. Cut into wedges and serve. Repeat with remaining quesadillas. Serve each wedge with a dollop of cilantro yogurt “sour cream.” Makes six.
