Snap ends off green beans (I do this the night before to make preparation easier)
Cook bacon until halfway done (also do this the night before if you wish) Once bacon is cooled, chop into small chunks.
In the pot of a slow cooker, add in all ingredients and stir to combine. Depending on the size of the slow cooker, you may need to add more water to ensure beans are halfway covered.
Replace lid and cook on low for 8-10 hours, or until beans reach tenderness desired. I like mine very soft, but others prefer theirs to be slightly crunchy.
