Soak beans overnight in cold water. Drain. Cook them for about half an hour in water so they slightly change colours.

Brown meat chunks with, fine chopped onions in 2 tablespoons of margarine until the meat absorbs its juice. Add tomatoes or tomato paste and continue browning. Add some water and cook until tender. Then add drained beans and, if you wish, red pepper. Cook on medium heat. Add salt when almost done. Serve with rice.
