Until recently I also use to cook my pork chops too long and they came out tough and dry. Now, if I am breading them and frying them in just a bit of oil, I usually only cook them for about 4 minutes per side for an average size chop on med. to med. low heat. I keep checking them with a fork after turning and take them out when the fork goes in easily. I like them much better now that they taste like pork instead of shoe leather!!!
