4small/medium boneless, skinless chicken breastsabout 8 to 10 ounces each
4thin slices deli hama scant .25 pounds
3ouncesfreshly shredded GruyereSwiss, or white cheddar cheese (about 3/4 cup)
Preheat your oven to 375 degrees F. Generously coat a 9x13-inch baking dish with nonstick spray. In a wide, shallow bowl (a pie dish works well), stir together the breadcrumbs, Panko, Parmesan, garlic powder, onion powder, salt, and pepper.
In a separate wide, shallow dish, beat the eggs.
Working one at a time, place a chicken breast on the cutting board with the presentation (smooth) side down. To keep things tidy, cover with a large piece of plastic wrap. With a mallet or rolling pin, gently pound the chicken breasts until they are each 1/4-inch thick (it will seem very thin, but will be easy to roll this way. Be careful not to hit too vigorously for as the meat becomes thinner, it may tear).
Top each chicken breast with 1 slice of ham and 3/4 ounce (3 tablespoons) cheese.
Starting on the narrower side, roll up the chicken like a sleeping bag, tucking in the ham and cheese as you go. Secure with toothpicks (I used about 2 per breast).
Arrange your work station in the following order: rolled chicken, beaten eggs, breadcrumbs, baking dish. Working one at a time, dip each piece of chicken into the eggs to coat, shaking off any excess.
Dip the chicken into the breadcrumbs, gently patting as needed so that the crumbs adhere to all sides. Place in the prepared baking dish.
Lightly mist the tops of the chicken with baking spray. Drizzle with melted butter.
Bake for 30 to 35 minutes, until the internal temperature of the chicken reaches 155 to 160 degrees F on an instant read thermometer (chicken is considered cooked at 165 degrees F, but the temperature will continue to rise as it rests). Let rest 5 to 10 minutes, remove the toothpicks, then serve.
TO STORE: Refrigerate chicken in an airtight storage container for up to 3 days.
TO REHEAT: Gently rewarm leftovers in a baking dish in the oven at 350 degrees F or in the microwave.
TO FREEZE: Freeze chicken in an airtight freezer-safe storage container for up to 3 months. Let thaw overnight in the refrigerator before reheating.
