Easy Parmesan Crusted Chicken

½ cup mayonnaise

¼ cup grated parmesan

4 boneless, skinless chicken breast halves (I flatten to even thickness with mallet)

4 tsp Italian panko

Arrange chicken on baking sheet. 

Combine mayonnaise and parmesan and spread on chicken. 

Sprinkle with panko.

Bake at 425 until thoroughly cooked, 15-20 minutes depending on thickness of chicken.
