These are great served with the Texican Shredded Pork recipe I've posted as a topping on tostados, but its also good in burritos or as a side for fajitas or enchiladas. Originally from a September 1989 issue of Bon Appetit that featured a "Do It Yourself Tostado Party" in the Cooking for Friends section. Queso fresco is also know as queso blanco and can usually be found in the cheese department at the deli section of your local grocery store. Monterey Jack is a readily available substitute. The overnight soaking of the beans is not included in the prep time.
