I totally cannot use olive oil, it makes me break out and leaves my skin a mess! Most olive oil I find at the store is rancid upon purchasing anyway. Any amount of heat to it (especially sitting in the trucks in the summertime) will make it go bad. That's why I don't get why so many people cook with it.
