These are just wonderful. I originally found this on the back of a package of fresh Thyme. I have made a couple of changes to it and the way it is cooked. If you want something good and just a tad unusual give this a try. It doesn't take much 'thyme' :-)
Mix celery seed, herbs, salt and pepper in a 1 gallon plastic bag. Shake the pork chops in spice mixture and set aside for 10 to 20 minutes at room temperature.
Meanwhile melt butter in pan over medium heat, add onions, apples and brown sugar in the pan and simmer for 5 minutes. Cover and leave on very low heat.
Grill pork chops on a medium grill for about 15 minutes. The meat is done when when firm to the touch or internal temperature reaches 150 degrees. Bring apple mixture back to heat. Add pork chops and let cook, about a minute or so on each side.
To serve place pork chops on a couple tablespoons of apple mixture and top with a tablespoon more and pour a little of the pan juices over the top.
