@jcboy,
Potato chips are a good choice. You can experiment with some of the flavored ones too. For instance, those malt vinegar flavored ones make a great breading for some types of fish and barbecue chips make a great coating for pork chops or chicken breasts.
Other "breading" alternatives you can try are chopped nuts such as pecans, cereals such as corn flakes, saltine crackers, cracked pepper.
Just do the usual dipping in flour, then egg, then the alternative breading.
