Rub roast with garlic salt. In small pan, sauté onion in butter. Add the rest of the ingredients which have been blended together. Pour half of the mixture over the pork roast. Cook roast at 325 degrees until meat thermometer reaches 180 degrees. (I add the remaining sauce when I baste the pork, every half hour or so.) This is a meat course that can be prepared the day before and reheated. In that case, I reserve sauce to add when reheating. Serve with rice.
