Spray the Crock Pot with nonstick cooking spray and add the ham hocks to the bottom. Sprinkle the salt and pepper on top.

Rinse the green beans and add them to the slow cooker.

Next, add the diced onions.

Pour the chicken broth over the green beans and ham.

Add more water if needed, to cover the green beans while cooking.

Place the lid on top and cook for eight hours.

After eight hours, remove the ham hocks and shred the meat. Remove the bones and fat, if desired.

Return the ham to the slow cooker and serve.
