Combine everything except for the tortillas in a bowl and stir to combine.
To make Quesadillas: Preheat a medium-large skillet over medium heat. Lay tortilla into hot skillet and sprinkle half a side with about 1/2 of the chicken mixture and spread evenly over the tortilla. Top with remaining tortilla.
Cook over medium heat until the cheese gets melted. Carefully turn with a spatula and cook the other side for about a minute or so, just to crisp the tortilla up. Cut into 4 wedges and enjoy. Repeat the process with the remaining tortillas.
