If your cutlet is thick, you might want to pound it. To do this, place the chicken breast between two sheets of plastic wrap or parchment paper (or in a zip-top bag) to keep things tidy. Use a meat mallet, rolling pin, or even the bottom of a heavy skillet to gently pound the chicken to an even thickness of about ¼ inch. Working from the center outward helps prevent tearing, and keeping the thickness uniform ensures the cutlets cook evenly and stay tender.
Add your fry ingredients to 3 bowls: flour, eggs and panko. Add everything but the bagel seasoning to the panko breadcrumbs and stir until combined. Starting with the flour, then eggs, then panko, coat chicken slices. Transfer to a plate and repeat with remaining slices of chicken.
Add fry oil to a large skillet. When oil reaches 350 degrees, add chicken. Cook for about 3-4 min per side or until chicken is a deep golden brown. Transfer to a cooling rack.
Turn oven to broil and top chicken with sliced of mozzarella. Broil for about 3 min or until cheese is browned and bubbly. Add bread for the last minute or so.
Make the slaw by combining ingredients in a bowl. Season to taste.
Toast bread and add chicken along with a heaping spoonful of slaw. Enjoy!
