Here's a recipe I like from Jeff Wheeler aka Bigwheel.
2 lbs washed pintos
1/3 lb salt pork..few strips bacon..or pork hock
2 split japs or serrano peppers
3-4 garlic cloves
1 T. dry mustard
1 T. wooster sauce
3 T. chili powder
1 can extra Hot Rotel Tomatoes with Habs
salt and pepper to taste
Cover beans with 2" of water and soak 1 hr. Drain and refill to same level. Add the salt pork and bring to a rapid boil. Reduce heat and put on the lid. Simmer till nearly done but not quite then add the other stuff. Once you add the tomatoes they dont tender up any more. Add water anywhere along the way if they get too dry. Veggies can be chopped..purreed or floated. If you aint into heat too strong..use only half a can of the tomaters.
