Stir in the tomato paste, pepper paste and grated tomato, and fry for 2 minutes.
Add the beans and pul biber, pour in enough hot water to cover by two fingers, and cook covered over low heat for 1-1.5 hours, until the beans are creamy-soft and the meat is tender.

Tips
With canned beans it's ready in 30 minutes: braise the meat tender first, then add the beans only at the end.
Also often made without meat, just with olive oil.
