With a sharp knife, cut each chicken breast in half lengthwise to create two thinner pieces of chicken, season both sides with salt and black pepper and set aside.
3 boneless skinless chicken breast
In a bowl, mix mayonnaise, water and mustard until combined. In another bowl, mix panko, salt and paprika.
¼ cup mayonnaise, 1 tablespoon dijon mustard, ½ teaspoon paprika, ½ teaspoon salt, 2 tablespoon water, 1 cup Panko breadcrumbs
Now, dip each slice of chicken in the mayonnaise mixture (make sure it is evenly coated with the mixture), then into the panko mixture (press lightly on each slice).
Place the breaded chicken slices onto a baking sheet. Spray with the cooking spray and bake for 20 - 22 minutes, or until you enter a meat thermometer in the center of a chicken slice and reach 165 degrees F.

Notes
Cut the chicken breasts into uniformly thin pieces to reduce cooking time and ensure that the chicken cooks at the same rate throughout.
