My mom made a delicious dinner from her Rival Crockpot model #3154 (we're pretty sure that was the one she used) and has since misplaced the little cookbook. It was called Italian Pork Chops, it had onions, tomatoes, obviously pork chops - and the meat was fall-off-the-bone tender. If you have the recipe, our family would be SO HAPPY if you could share it with us. :) Thank you!
