The 'Whiz-Wit' Dip
Chip steak is traditionally made from rib eye or top round steaks. You could also use a cheaper steak to not break the bank. The steaks are cut VERY thin, making it easier to cook for cheese steaks. It's found in most lunch meat counters in the Philadelphia/New Jersey regions but could easily be made at home. I've seen Lancaster Brand in my grocer's freezer that would work well with this. Using Steak-Ums(R) brand chip steak may leave your dip extremely greasy!!
