Place pork into a resealable gallon bag and seal shut. Use a meat tenderizer to flatten cutlet to about 1/4" in size. Repeat until all cutlets are flat.
Fry in a pan for about 6 minutes or until golden brown. Drain on paper plate. Top a roll with mayonnaise, add cutlet, lettuce, tomato, onion, and pickles and top with remaining roll. Serve immediately.
