Cut the chicken breasts in half. Place one half breast at a time between a large piece of plastic wrap. Beat the chicken with a meat mallet or a heavy rolling pin to thin the chicken out and tenderize it.
Place the chicken in a large bowl and pour pickle juice over it. Let it sit while you make everything else (about 15 minutes) , or you can marinate it for up to 1 hour. Be sure to turn chicken over once throughout the marinade.
While the chicken is marinating, add cornflakes, seasoning and Parmesan to a small food processor or high speed blender. Pulse until you have a bread crumb looking texture. Add the mix to a plate or a shallow, wide bowl.
In another bowl, add the eggs, hot sauce and whisk. Preheat the oven to 425° F. Line a baking sheet with parchment paper. Add wire racks (if you have them) to the baking sheet for ultimate crispiness. If you do not have a wire cooling rack to use that it ok.
Dredge the chicken through the egg mixture then through the cornflake crumb mixture, covering fully and heavily. Place on the prepared baking sheet or on the wire racks on the baking sheet (see photo). For a thicker coating, dip the chicken back through the eggs, then through the crumbs a 2nd time. Spritz with oil spray (any will work) Bake for 20-25 minutes, until crisp all around.
Toast buns, mix up the lettuce "slaw" in a large bowl. Construct the burgers and enjoy!
