Collard greens are a staple in soul food cooking, and in this recipe, simmering the greens in a pork broth really intensifies the flavor. To make preparing this dish easier, try and find washed and chopped collard greens in the supermarket. These bags eliminate the hassle of washing and removing the stems of each collard green leaf. If you cant find the bags, strip the leaves to remove them from the center ribs before washing and chopping.
