You want to make the chicken as even as possible thickness-wise (a meat tenderizer is great for this). Use canola oil, medium high heat and don't crowd the pan. Once you put the chicken in the pan, let it cook for 5 minutes without moving it to get that nice sear, then flip it over for another 5 or until a meat thermometer reads 165. Last but not least, finish it by melting a little butter in the skillet and spooning it over the chicken. Deliciousness!
