Cook your soaked pintos from scratch...my secret is to cook the beans in beef stock with ground cumin. Drain the tender beans, reserving some of the stock. Put 1/2 cup bacon grease into a large skillet, get it good and hot and add in the beans. Using an old-fashioned potato masher, go to it, stopping occasionally to add a cup of fresh salsa. Add bacon grease and salsa with an occasional splash of the reserved stock, until they have the consitancy that you like. Yummy! Does it take a good while? Yep! Is it a labor of love? Yep! Is it worth it? YEP!!!
