Pick ends off green beans and snap or cut them into 1-inch pieces. Meanwhile, slowly, over medium-low heat brown bacon in wok or medium size covered frying pan. Add the beans and stir occasionally until all of the beans have changed color (the green gets brighter and they look sort of opaque). Add broth or water and sprinkle on salt and pepper. Cover and simmer for 10-15 minutes (depends on how done you like your beans). Serve immediately or remove from heat and rewarm when ready to serve.
