I can guarantee a cubed pork chop will not be as tender or as tasty. A frozen one will not be as good as a fresh hand pounded one.Just get your meat dept to cube boneless pork chops (pork loin) if whole cut 1” thick and salt/peppper flour like cube steak.a lot of people will egg wash before flour or dip in buttermilk.while you there get them to cube pk of boneless chicken breast and do same way—— you can think me later
