Combine the flour, cornstarch, seasoned salt, and pepper in a shallow baking dish. Remove and reserve 2 tablespoons of this mixture. In a second shallow baking dish, whisk the eggs and milk together until well-blended. In a third dish, combine the crushed crackers and panko, plus the reserved flour/cornstarch mixture.
Butterfly each pork chop and pound between sheets of plastic wrap with a meat mallet to ¼-inch thick.
To coat, first dredge each piece of pork on both sides in seasoned flour, shaking off any excess. Dip into the egg mixture to coat both sides, then dredge in the crumb mixture, pressing gently to coat both sides evenly. Transfer the pork to a clean plate and repeat the process with the remaining pork. Allow the pork to rest for 20 minutes to give the breading time to adhere to the meat.
In a large, heavy-bottomed skillet heat the oil to 350°F. Fry the breaded pork until golden brown on both sides, about 3 minutes per side. The pork is cooked when it reaches an internal temperature of 145°F on an instant read thermometer. Transfer to paper towel-lined plate.
In a skillet, toast the buns over medium-high heat. Serve pork loin on buns with condiments of choice.
