Spray slow-cooker with nonstick spray and add enough water to just cover the bottom of the crock and place pork chops directly into the crock; there's no need to brown them. In a saute pan, melt the butter; Add the garlic and chopped onions; cook over medium heat for about a minute. Add bottle of chili sauce, brown sugar, mustard, salt and jalapeno peppers, if desired Cook mixture until bubbly, stirring constantly and pour over chops in slow cooker.

Cover slow-cooker and allow pork to bake for about four hours. Remove lid from cooker and de-bone chops, pulling the meat apart with two forks Cook for another hour or so until enough liquid has evaporated from the barbecue sauce to allow it to thicken a bit. Serve onto hamburger buns or onion rolls with a slotted spoon. Makes about eight sandwiches
