Keep pork loin roast juicy and moist by cooking in the slow cooker or crockpot. Onions, garlic, balsamic vinegar, brown sugar and soy sauce combine to make a flavor bomb of a sauce! Let slow cook all day and you've got dinner ready as soon as you get home from work. You can also use pork shoulder or pork butt. Slice up leftovers for lunch prep or make pork sandwiches.
