In a small bowl, combine mayonnaise, cilantro and lime juice and stir to combine.

In a large bowl, combine chicken, beans and mango and stir.

To assemble burritos, spread each tortilla with a heaping tablespoon of mayonnaise mixture, leaving a ¼-inch border around the edge. Place about 1/3 cup chicken mixture in the center of each tortilla.  Tuck in the sides and then wrap and roll the tortillas.
