melt in your mouth chicken breasts

This chicken does what it says.  It is incredibly tender and flavorful and so quick to throw together.  I took some to a friend's family and they tried to determine what the flavors were.  I was hesitant to admit what they were but since they all liked it so well I figured it would be okay.  I did use light mayo...

4 boneless skinless chicken breasts (I filleted them)
1 cup mayo (I used Kraft light made with olive oil)
1/2 cup freshly grated Parmesan cheese
1 1/2 teaspoons seasoning salt
1/2 teaspoon ground black pepper
1 teaspoon garlic powder

Mix mayonnaise, cheese and seasonings.  Spread mixture over chicken breast and place in baking dish.  Bake at 375 degrees for 45 minutes.
