In a medium sauce pan saute the onions until very dark over medium heat. Be careful not to burn them. Add all other ingredients and bring to a boil. Reduce heat to a medium boil and continue boiling until the sauce is thick and reduced by 1/2. Remove from heat and serve with the marinated, grilled chops. Pork is fully cooked at a temperature of 150 degrees, so try it that way. It is completely safe while still juicy. Just remember the juice must run clear and not be red or pink. When pan frying chops try to maintain a temperature of 325-350 degrees and turn chops over when they are golden brown.
