Crockpot Smoked Sausage,Green Beans and Potatoes

1 lb kielbasa or smoked sausage
4 med. potatoes, peeled and cubed ( I used red potatoes, cubed with skin on)
1/2 med. onion, sliced
2 14.5 oz cans green beans, drained
1/2 t. Black pepper
Salt to taste

Combine all ingredients except sausage and place in crockpot. Add water ( I used chicken broth and water for,extra flavor) to barely cover ingredients. I also added a tablespoonful of bacon grease for more flavor. Cover and cook on low 4-6 hours until potatoes are done. One hour before ready to serve, cut the sausage into bite size pieces and add to top. Do not stir! Mix before serving. Great served with cornbread.
