Line a rimmed baking sheet with parchment paper. Line a second baking sheet with a wire rack topped with paper towels and set aside.
Slice pork chops in half, lengthwise. Pound the pork chops to about ¼ inch thickness using a meat mallet or heavy skillet.
Place flour into a shallow dish and mix in garlic, salt and pepper. Beat the eggs and milk in another shallow dish and the cracker crumbs into a third dish.
Dredge pork cutlets in flour. Dip into the egg, coating both sides, and then dredge through crushed ritz crackers.
Place on the lined baking sheet in a single layer.
Heat vegetable oil in a heavy bottom skillet over high heat using a fry thermometer, heating to 375°.
Fry breaded pork chops 2 at a time, turning after about 2 minutes.
Turn and continue to cook another 2- 3 minutes or until pork reaches 145° using a digital meat thermometer.
Remove from the oil when cooked through to the paper towel lined wire rack.
Toast the buns, spread with mayo and top with lettuce and tomato. Season with salt and pepper. Slice the pork in half lengthwise if using hoagie buns and place onto the buns.
