Heat a pan up that will be large enough for 4 tortillas.
Season with Cajun spice. Cut into slices, you can cook whole but it tase longer. Place Chicken in pan and cook, make sure to flip and cook all the way through. Once cooked, place on a plate or clean cutting board.
Heat up the olive oil in a pan (I use the same pan to get the left over spice from the pan. lay down 1-4 tortillas (we do 4 at a time).
Add the chicken and cheese and close the tortillas.
Cook until light golden brown then using a spatula flip and cook until the other side is slightly brown.
Plate the quesadillas and add sour cream, guacamole and salsa if you want. Enjoy
