Soak the beans overnight (at least 8 hours) in water, or use the quick soak method.
After the beans have soaked, drain them and add to the slow cooker.
Set a medium sized skillet over medium high heat on the stove top. Add a bit of cooking oil. Add the sliced kielbasa and brown them on both sides. Add to the slow cooker.
Add the remaining ingredients to the slow cooker. Stir.
Cover and cook on low for 8-9 hours without opening the lid during the cooking time.
Remove bay leaf and serve.
Enjoy!

Notes
Note that I didn't add any salt. Between the salsa and the chicken bouillon cubes, to my taste this did not need salt. Add salt to taste if desired.
