Every cook can appreciate the convenience of a delicious slow cooker meal. And on a cold day, most will appreciate the comfort of a pork goulash. This hungarian stew is loaded with flavor, and the preparation is relatively easy. Quickly saute a few of your ingredients, toss in the rest, set your slow cooker, and come back to a hearty, warming meal. A little sour cream is the secret ingredient in the sauce and adds to the richness of the dish. Feel free to substitute half of the pork with beef if you prefer.
