Preheat your oven to 375. Slice your chicken across the top but not all the way through. I didn't get a picture (I don't know what I was thinking).
Mix mayo with all of the seasonings. Add the parmesan cheese and mix again.
In a 9x13 Pan, place your chicken breasts. Divide the cheese mixture on top of the chicken breasts evenly.
Once spread evenly, bake for 25-35 minutes, until the chicken is cooked to the proper temperature.
Allow to cool for a few minutes. Slice the chicken and place on a plate. Top with some of the cheesy goodness that fell to the bottom of the pan. Serve hot.
